No consequential performance increase over simply bypassing the resonator. Just sound and cosmetics.

I've used K&N drop ins since 1992 with no problems to any of the engines. yes, there may be limited or no hp or mpg gains, but that's not the real reason I install them. I keep my cars for ten years or longer. Way longer than the break even point of throwaway air filters.

Chrysler is now denying warranty claims when they discover turbo damage and dirty or "dusted" intakes in Cummins diesels. It just so happens that in 95%+ of those cases, a K&N filter is used.

Not on my turbo engine.

Regardless of the procedure necessary, it isn't worth the headache for a 1-2hp increase. It just isn't. There is no point to it when actual warranties have been denied in other engines due to the use of these filters.

I'll stick with my tried and proven dry filters. As far as intakes go, the Injen intake is the only valid option since it uses a very good Amsoil EA filter. Last I checked, the ZZP intake uses a K&N filter.

IF you notice any power gain, it is just because it "tricks" the mass airflow sensor (air passes the sensor element differently), probably causing your truck to run lean.

Many people also remove a very dirty filter when they install a K&N.
