G'day guys,

Just wondering does anyone know which is the correct k&n filter replacement part number  for a 2016 i30 CRDI?

The k&n website gives 2 different part numbers, but both for fuel injected, 33-3008 and 33-2451.

  That's confusing!

Sorry I don't hopefully somebody will.

If you contact them with your VIN they should tell you which.

Awesome, will do, thanks mate

If you click on the part number link you'll get the sizes shown below, I'm pretty sure your one will be 33-3008 for the diesel as the other one is the type I have in my petrol.

Ralphy,just remember that changing from a standard to high flow filter MAY void your warranty

Only if there were a fault directly caused by the filter (highly unlikely) like never being cleaned to the point it was so blocked the car couldn't breath
