Author Message   JJohnston Posted on Sunday, February 02, 2003 - 09:41 pm:    somewhere on the web i saw a cylinder type k&n air filter attached to a curved intake pipe that mounts to the intake plenum on a D90. this is not a snorkel deal, but rather an under the hood arrangement and the k&n filter was exposed. supposed to increase gas mileage and performance. anybody had any experience with them and/or know where i can get one?
