Cold Air Intakes

[blackbetty]

i installed the pd160 and cleaned out my k&n filter. and there is a nice difference in airflow to the motor now, is certainly feels like it breaths better and has a crisp rev in the higher range. Keep in mind that i still have a stock ECU and exhaust.
one more thing, i was looking at the piece that the pd160 clicks in to (the one that screws into the car) - and i thought it too looked a bit restrictive, so i cut out the plastic bit and now the opening has more area/cm2 than the pd160 intake trumpet. without cutting that plastic flap, it would have been about 1/2 the area.

next on the list is a downpipe (using the factory cat and exhaust)....improve the breathing in the motor, should also improve the breathing out

You won't feel much difference if you are using the stock cat.... That is where most of the restriction is.

ah yeah thats a really good point. i might hold off then and save the pennies for a full exhaust.

Sorry for creating another thread.
Anyway, ITG has a flatbed for our 9N3s they also have a CAI system.
Just waiting on pricing.
