If you want a KN drop in, I've got one I'll sell you. I bought it and was pleased with it, but now I've got the mod bug and want to get an AFE stage 2 CAI. I paid $51 for it, still have the receipt, bought it June 2. I'll sell it to you for $30 and include free shipping. Its only got 3000 miles on it. PM me if you're interested.i just changed my air filter tody while i was at lunch - i bought the mopar one from the dealer for 20 bucks.... should i have bought the k&N drop in? does it make much of a difference if any in performance/sound?
