check engine light

Put the factory air filter back & see if the check engine light turns off. If it does call S&B & tell them their cold air intake is defective.

Mine did this periodically after S&B. It's a DPF below efficiency threshold code most likely. It's a phantom code that causes no harm. I have a Spartan so I cleared it whenever it came up. I take it you still have DPF on. get that joker off with tuner and problem goes away. S&B really is the best CAI available for performance, fuel efficiency and particulate filtering IMHO. I did tons of research before purchase and saw some pretty bad things about AFE letting too much dirt in. My fuel mileage is up almost 2 MPG since install, and before I put on CAT/DPF delete.

basicly the code is caused from the filter flowing too much air (map sensor seeing too high readings) and then when it goes to regen the regen temps are too low.. which is greatly afected by the intake due to the engine firing on the exhaust stroke as aposed to a remote location in the exhaust like the larger diesel engines do.. (detriot,cummins,cat,etc...)
