I might be a victim of a counterfeit air filter I guess. My problem is still unresolved so I can't say. (they've had my truck for 5 weeks waiting for a DPF) I currently have the AA filter in the truck that I got from Amazon. (engine light stayed on) Dealer says the filter can't have glue strips, and the last I heard from them, there is a new version of the AA without glue strips. Of course they didn't have any. I've been complaining about all this to RamCares recently and they have told me that the dealer now has the air filter that I need...we'll see. They are supposed to get the DPF today, not holding my breath...heard if before.
