Below are pictures of the K & N install I did on my 2011 Durango Citadel. The K & N removes the stock plastic Air box and plsatic baffels in the fromt of the engine. It opens up the engine compartment. The install was easy and straight forward.
I have the same kit on my 2011 Durango R/T. I didnt like thathe crankcase breather adapter is so close to the pulley assembly 1" and the breater hose prevented the Hemi engine cover to seat properly and the air tube rests on the refridg. line. What do you think.
