Title: Induction Kit
Post by: CraigB on September 22, 2014, 08:11:53
This is the biggest useless piece of crap contraption that came out

And this is the tidy little kit that replaced it

Yep, it's still got the breather attached and a filter.

The police tried to question my HSV once and when I pointed out that it was filtered you should have seen the look of disappointment on his face :snigger:

So how relevant is this to an FD and how much does it cost? :D
Title: Re: Induction Kit
Post by: CraigB on September 22, 2014, 09:13:00
I got the kit from here http://k-tuning.com/en/zeo-avante-md-new-accent-veloster-k3-air-intake-pipe-kit-filter.html (http://k-tuning.com/en/zeo-avante-md-new-accent-veloster-k3-air-intake-pipe-kit-filter.html)

Not sure about fitment for FD's, but I'll check a few sites and see what I can find, not sure if it would be possible for the turbo diesels though :undecided:

Post by: The Gonz on September 22, 2014, 09:17:01
Ah, saw GDi in the picture and it still didn't click. I don't expect it will be anything similar at all for a Diesel, especially with turbo involved. :confused:
Title: Re: Induction Kit
Post by: CraigB on September 22, 2014, 09:48:11
No kits out there I can find for a turbo diesel Gonz :(

The pipes and connections can all be bought individually from Auto Pro and Supercheap so it would be possible to make something up with more direct and better flow than stock if you were keen, I probably would have made one up if I hadn't come across this kit.

Unless there is a failure directly caused by the modification warranty should still apply.

How does this mod affect your warranty
As cruiserfied said it doesn't affect warranty, I ask these things before I do them :wink: technically the new filter has better filtration as well with a HKS triple layer filter.

There also is no failure that can be caused by this change unless you happen to damage something in the removal of the old intake assembly "a quite involved process" but once the passenger front wheel is removed - then drop the left hand front inspection panel that secures the wheel well to the bumper it is fairly easy access in behind the wheel well to remove 2 hidden bolts securing part of the OEM filter box to the chassis rail.

I also cant see a reason for the lower secondary box other than Hyundai thought there was some vacant space so lets fill it with unnecessary junk, the lower box must have had over a thousand bugs in it and no service panel for cleaning so eventually it would have been full to the brim with bugs and then starting to restrict air flow even more :rolleyes:

What about sucking in the engine bay hot air? Thought cold air induction was better for combustion? Does it go any better? Better fuel economy?  Are you getting fresh air from behind the head light? Looks a lot better than the tangled factory air intake.  :goodjob:

Title: Re: Induction Kit
Post by: CraigB on September 23, 2014, 21:42:21
These engine bays don't get that hot, with the exhaust being at the rear of the engine the heat is reasonably well directed away from the intake and once you are moving there is so much air pouring in through the front of the vehicle it wouldn't matter...the intake pipe can always be extended down into the lower left area behind the bumper if there were any heat problems.

Definitely goes better, as mentioned it has eliminated the flat spots and gives much better throttle response, not sure about the economy yet as it's only been on for 2 days with short 2km trips back and forth from the train station so I'll check that more on my next tank refill and a good weekend drive.

Theoretically with better air flow the economy should improve "minimally at least"  always had great results with all the other cars I've done the same thing to :)

I took the car for it's first decent drive today ( since installing the intake kit ) down to Bunbury and back, about 340km's all up and very little traffic.

The car performed well as usual with the added benefits of slightly more power/ better acceleration and a very minimal improvement in economy when compared to the exact same drive performed some months ago, driving style was mostly easy cruising in 5th or 6th all the way except for stopping to have lunch at a friends house in Bunbury.

Previous trip with standard air box averaged 4.8 L/100,  this trip was 4.6 L/100 so not to much difference on the overall average but I've never been able to get the usage down to 4.6 L/100 on any occasion previously so it is a little better on fuel considering the bit of extra power I'm getting as well.

I've been doing some tinkering/testing of different filters since installing the induction kit, so far the K&N xtreme filter pictured below has the best notable improvement over the filter supplied with the kit.
The original intake pipe an filter that came with the kit was an improvement in torque and power when compared to the factory intake setup but I felt that the triple layer foam filter was still quite restrictive so I decided to test the K&N xtreme and the difference was immediately noticeable, the torque has really increased now and you can actually feel it pulling much harder.

If you decide to get one Dazz I'll give you the model number of the additional K&N filter I purchased if you want it, be warned though the K&N costs nearly as much as the kit itself :Shocked:

You can get the SAAS filters for about $15 but then you need an additional reducer to make it fit the induction pipe and I couldn't find one to fit 63mm so I just bit the bullet and said stuff it...get the K&N, you can of course stick with the HKS filter that comes with the kit as it is still a marked improvement over the stock system but as I mentioned previously the K&N is on another level.

I haven't seen these setups for diesels, if the main induction pipe is similar to the i30 diesel then you could possibly get an adapter and fit a pod filter to the end so it is situated down behind the headlight where it can draw fresh air from.

What speeds were these, more or less? I had to laugh today, I had to go out of town to a client. I drove about 110km into a fierce 70kph headwind. The poor i30 struggled to keep 120kph, and when I got there my OBC pegged my consumption at 12L/100km. On the way back with a nice tailwind I managed 6L/100km, so the two trips evened each other out :goodjob2:

The reason I am asking is that with 70% Highway/30% City driving I mainly stay around 7.6 - 7.8L/100km no matter how I drive and I was looking to improve it a bit
Title: Re: Induction Kit
Post by: CraigB on November 04, 2014, 12:14:53
Speed was mostly 100-110kph the whole way there and back except for a couple of lower speed suburban areas, no stop starts which is why I was able to achieve 4.6 for the trip.

My driving is probably a 70%/30% like you but my averages are about 6.2 - 6.5 and more around 7.5 if I just do short stop starts with no HWY driving.

If you're trying to sit on 120kph that's probably why you used so much fuel, your above the optimal working range of the engine and it's labouring harder.

My 1.6 is a little different to yours as well, slightly higher kw's and different gearing I would think so that has to be taken into account also.

I agree 1000% with the comment about the gearing - to me, it seems like the Gamma engine has a sweet spot between 3800 and 4200rpm, but this rev band doesn't really help the fuel economy, especially not with the 5spd gearbox like I have. 120 on the speedo is around 3700rpm, so actual 120 as per a GPS would probably be around 3900 - which I think is a bit high, but then again I come from a Honda that sat at 3200rpm @ 120 so I am a bit biased :mrgreen:
Title: Re: Induction Kit
Post by: CraigB on November 04, 2014, 13:37:28
Not sure where mine sits at 120kph, somewhere around the 3 mark I think.

Sweet spot for torque might be between 3800 - 4200 but that's not the economical sweet spot, around 2500 is where I like to sit on.

Hippo feels very weak at 2500rpm, but also she has some high mileage on and the terrain I do isn't very flat.

My next vehicle will have to have a 6spd at least :mrgreen:

 :Shocked:
At 120kmh + 70 kmh headwind, you had a 190 kmh velocity of wind hitting the frontal areas of your car and the subsequent drag over the body. Not surprised you were consuming 12l/100. Anything over 80kmh in total and the wind starts to severely affect performance and economy.

Yip, and considering that wind force increases exponentially and not linearly it makes a huge difference as well. But they do call Port Elizabeth the Windy City so I guess I should probably get used to it :(

In line with Phil's good guidance, 80kph is when drivers should switch from open windows to air conditioning on hot days. The improved aerodynamics of closed windows outweigh the load of operating the aircon. :victory:

Ok! I got some time to play at a friends dyno shop today and came up with some interesting results.

Stock standard the 1.6ltr is 98kw - 131.32hp as stated in the spec's ( not dyno tested )

The intake kit I installed shown in earlier pictures showed results of 102kw - 136.68hp, a definite improvement but I was still feeling a lack of response " flat areas" when under load "acceleration"

Today I changed around the intake components to a much larger SAAS filter 5.5" x 6" with a 76mm connecter ( previous K&N filter was 4"x 4" with a 63mm connector ) changed the intake pipe to 76mm x 250mm polished Aluminium ( previous intake pipe was 63mm x 300mm polished SS ) and used a 76mm to 63mm silicone connection to the throttle body plus fitted the breather connector to the new pipe which was sacrificed from the old pipe.

Ran her up on the dyno and the figures improved again with a more harder and constant pull through the rev range with a nice growling sound to I might add :cool: , now it's 105kw at 140.7hp so all up a 7kw - 9.38hp gain over stock and the later "new' kit was put together from Supercheap for a much smaller sum of $80 :D

Another place you could try is :link: Filters Elite - Streamlining your solutions (http://www.filterselite.com.au/) the guys here are extremely helpful and if it's a filter you're after they can get it... and probably at prices cheaper than anywhere else, they also manage to obtain just about anything you could want as they brought in some Eagles statues a little while ago that a guy wanted to stop all the pidgins crapping on his house and cars.

Pod filters are illegal because of noise pollution, the cop thha . Pulled you over and let you go because it was filtered had no idea.


The extra's in the intake are for reduction in induction noise.


Looks awesome. Another thing you guys can have a crack at for the same effect less the bling can be a k&n panel filter, fits in standard box, gives a similar response increase and better fuel economy but no induction noise.

And for the diesel guys. I've just thrown a pod filter on the end of my AFM for shits and giggles for the spooling noise. Soon to add an alloy pipe for dose 😅😅.

Sorry but you are wrong, they are not illegal as long as you retain the emissions breather pipe, the cop that pulled me over was correct and his decision concurs with a lot of my friends who work in the police force :)  they are also not noisy...very quiet to be exact and with a slight burble if you plant your foot, noise pollution is only of concern in the exhaust area ( and it would have to be bloody loud ) and blow off valves on turbos and possibly if you are squealing the tyres doing burnouts :rolleyes:

Panel filters placed in the original airbox make very little difference if any at all, the idea is to increase the airflow and retaining the stock airbox and intake pipe this cannot be done.
Title: Re: Induction Kit
Post by: Okkan on January 17, 2015, 07:57:26
Don't mean to seem like the smart arse noob typw but this is directly from the epa.  .

 "
When fitting your vehicle with a pod-type air filter you must ensure the fitting does not cause an increase in noise from the air intake system. The EPA considers that this type of modification is acceptable when the air filter element is effectively encased or boxed-in."

The police do not make the law. They enforce it. We have had cars come into work with defects for not having the shift pattern on the shifter in a manual (the actual law is an auto must be marked prnd12 I assume for the fact if your inhibitor switch is f****ed you don't run over the poor old lady in front of you whilst starting your car) just one very quick example of HWP having no idea.

Pod filters do increase the noise because your once muffled with airboxes and standard piping induction path is now open.

I agree with the panel filter part ... Sort of. The k&n panel filters DO make a difference in performance although definitely not as much as a well setup pod.

As you stated " When fitting your vehicle with a pod-type air filter you must ensure the fitting does not cause an increase in noise from the air intake system " and I'll repeat that the Pod Filter is very quiet bar the slight burble when you plant your foot, I've done these sort of modifications on many cars over the years and they are completely legal as long as you retain the emissions.

The only time I've heard an overly noisy intake was with the side draft webber on my Mini :D

Title: Re: Induction Kit
Post by: Okkan on January 17, 2015, 08:34:09
It also says

"The EPA considers that this type of modification is acceptable when the air filter element is effectively encased or boxed-in."

I've also done many mod's like this to different cars and work as a mechanic. You do get an induction noise whether big or small this is the law stupid it may be , but that is the way it is.

I have nothing against it. I do it myself. I'm just saying it may be best not to give some people the wrong idea about the legality. If you were to be pulled over by the EPA (which funnily enough does happen but I very very highly doubt would in a brand new car) you would be fined.


Nothing better then the induction noise of a worked, high comp, big cammed car by motor !
Title: Re: Induction Kit
Post by: CraigB on January 17, 2015, 11:17:33
@Okkan, I don't know how many times I have to repeat myself but Pods are not illegal as long as emissions are retained, I have friends in the Traffic and Pol-air sectors of the force and I completely know what are the legalities of after market modifications are.

There is no way in hell that one of these pods can increase induction sound in decibels that much to be classed as noise pollution ( which I believe has to exceed 165 decibels...the car (i30) itself would be lucky to reach 70 or 80 decibels ) , you wouldn't be able to here the induction over the exhaust if you had a car powerful enough to develop induction noise.

Another thing I may point out is I have one of these pods on my car currently and have tested on the i30 two different setups with three different types of filters and they are all very quiet, yes a little more volume than standard but still quiet and not loud enough to be heard over noisy tyres/road noise.

If in the unlikely event you did get some unwanted induction noise with a ram air system then it is quite easy to apply/fit a suppression canister but this wouldn't be required on an i30 or 90% of stock standard 4 cylinder engines because the volume of air being drawn into the throttle body just isn't enough to create a sound that would come anywhere close to being called a disturbance/noise pollution.

Post by: Johnno on January 17, 2015, 12:25:23
You guys down under don't half have some strict laws on what you can fit and not fit to your chariots.

My take on induction kits is that there is always a trade off from the OEM type's. Be it performance, emissions, fuel economy, filtration
Car manufactures spend a lot of money into R&D and they have to strike a balance. If these induction kits are all cracked up to what they say they be then the manufactures would fit them as standard. Don't get me wrong I'm not against them I've had about 9 of my cars fitted with a different type of air filter one way or another and even without and the others box standard

You will find that they can work better on some makes of car than others. Some engine tuners actually leave the OEM system in place and replace the panel filter with a high flow oiled panel filter to aid the filtration, you could fit them without oil but then you risk the chance of debris getting into the engine and after long use take can take its toll on the engine. Same goes for induction kits they are high flow and if anything gets in your engine your going to have a hard time trying to make a warranty claim. Believe me I've tried and failed to the tune of £1800

Don't want to sound like a grumpy old git , if mine wasn't in warranty it would also be getting a seeing too :lol:

Each of our states can vary on the specific rules as well, ( like radar detectors are legal here " Western Australia" but not in the other states ) makes it quite confusing at times :head_butt:

The Pod's are similar to the cotton gauze panels in respect to oiling, never use an un-oiled filter :goodjob2:

I'm going to simply agree to disagree.


Oiled filters you have to be careful with, with a car with an AFM make sure you don't go overboard with the oil as it can oil up the sensors.

True, always follow the instructions that come supplied with the oil and filter cleaner as it clearly explains how much oil to use :)

I don't want to throw oil on any fires, but as far as air flow is concerned engines need to breath....... But engineers restrict the flow to help with emissions and noise.

Basically, the air inlet on the filter housing needs to be at least as large as the combined area of the throttle body (bodies).

This means that the induction kits should be a beter option any day, but there's the increases in noise which seems to be illegal in Oz.

Simply putting an oiled filter in the standard airbox is just cheaper over the life of the vehicle but won't give anywhere near the power increase of a CAI.
