Title: induction kits
Post by: dalewhite on October 11, 2011, 11:28:33 pm

I need to make a new air pipe for a induction kit on my mk5 gti. does anyone know what diameter the aftermarket pipes uses ( im guessing its 2.5 or 3 inch) does it cause any problems with the air flow meter?

^^^ The section that the MAF runs through on the standard airbox isn't round it's oval IIRC. Most aftermarket intakes use a round pipe that matches the same surface area.

The oval measures 79mm by 53.5mm internally and the circular dimension from the intake is 75mm externally. I just measured my old engine cover. Hope that helps. Rob
