Is anyone familiar with the AC Schnitzer cold air intake for the 318ti? Is there a port for the 02 sensor?

i think you should try the fogged airbox mod, i actually just got the k&n filter and it sounds real nice, sounds like my car is fast lol but thats about it, im trying to find all the parts to my airbox so i can do the fogged airbox but i cant seem to find those big fat washer parts that you use to screw the airbox to the car lol but i cant find it. oh well i shall find an alternative. hey if you are gonna get rid of the airbox send on over the washers :D. but i suggest you keep the airbox for 3 reasons. 1, there is definatly a gain in hp, dynoed..and 2 also its cheap as hell and 3 it keeps the oem paper filter which you should replace to help the airbox. my $.02

I'm not fimiliar with the Schnitzer CAI. I have the Dinan CAI and it works great. It has all the factory sensor inputs.
