So first, I got my Injen CAI from r100s on wed. Yea it sounds awsome and performs even better. Now the down side to this is I have about 400 miles on the car since then and I just threw a CEL this morning on my way to work. I have a 06 SE V6 with the Injen CAI and custom Catback exhaust. Anyone know whats up with the CEL. The only thing I can think of is its going to tell me my engine is running lean. I checked everything and it seems ok. Going to use my friends scanner in the morning to see what the code is. Thanks for any input.
