Unless you want to dress up the engine bay, save yourself some cash and leave the intake alone. The Gen 3 will give you some gains, but cleaning the filters will require removing the bumper every time. I've had the K & N drop-in's for over 6 months with no oiling issues whatsoever. Most of those issues are from people re-oiling and applying too much anyways. There is a tread here with dyno results for the K & N drop in's with somewhere between 5-10hp rwhp gains.... about the same for the Gen 2's (nowhere near 15hp gain). If you want real gains, save your cash for an exhaust.
