I recently installed a customer 3" aluminum CAI on my '04 25rs. The additional power is amazing but now my check engine light is on! I think it is because I have a custom CAI? There was a sensor plugged into my air box that i am assuming was an intake sensor of some kind so is there a way I can bypass this sensor?

sounds like your car is an auto, its probably an intake temp sensor. . . drill a hole and plumb it up to get rid of the cel if thats what the case is.

I have an IAT on my RS as well. Just take a uni-bit and drill the appropriate size hole and reinstall it. You should be able to reuse the grommet from the OE airbox. The car needs that sensor for proper A/F ratios.
