Maybe a dumb question... but since Im a TT owner and need A4 info... figured I'd post it here.

anyone know the intake inlet diamter on an A4? HKS has a ton of the mushroom style high flow filters but they are categorized by vehicle, not by size. (WTF kind of bullsht is that?) So since the TT has a 3" inlet diameter... I need to figure out what other car has that same inlet diameter. They have one for an A4 though

-shrugs-

 

Wouldnt they all be the same since its the same motor?

 

No. I think your motor is a 2.0, mine is a 1.8t.
They aren't the same motor.

But if they were, then yea probably
