I took a survey on K&N'* site about my cars, and they sent me a letter and a sticker. It just today arrived, and I'm going to go clean my car and put this thing on. Oh, yes. Now, where does this go?

dang, i need one of those...

If you put on the drivers side rear window its good for 20hp, for some reason you only get 10hp if its on the passneger side...

Wait, I see this is in the lounge. What have I done?! Anyway, it'* too late. I put the sticker on the driver-side fender, right behind the wheel. I guess I'm going to have to rely on purely mechanical improvements for horsepower increases. Pity.
