Pays for itself.
Filter has a lifetime service life with regular cleaning. There is a small performance gain and with the 3.0L engine it is not wasted. This filter does not permit undue intake noise or resonance I have had great experience with K&N products.

K&N Drop ins for my Mercedes E55 AMG
After the install, took out the car for a ride. Def noticed a def w/throttle response when step on the gas pedal. Car seems to want to pull alot quicker and reach the rpms alot sooner than before. Cheapest price for hp gains!!!

May need 2
The dealer wanted $60 for replacing the air filter at my last service B on my C230 Sport. While I was in the waiting room, I got online (using their free wifi) and found this filter for less than that. Plus, it's basically a "forever" air filter! So I got it in the mail, took off the housing, and that's when I see two air intakes which have a filter for each side. Not such a good deal at first anymore, but it will pay for itself, just not as quick as I thought it would.
