Does anyone have a K&N cold air tube/filter on their truck? Bought a used 2015 with it and noticed a CEL came on the first day. The filter was dry so I cleaned it and oiled it. Scanner said air/fuel mixture was too rich...so not enough air. Cleared the code and it's been off since. Has anyone else had codes from an K&N system?

 

ditch the K&N and put the stock filter back in. It doesn't do anything anyway.

 

I would but the entire air filter housing is gone. The previous owner replaced it with the entire K&N CAI kit

 

I'm sure you could find one at the pick n pull
