I got the ASA intake from PDR yesterday and installed it this morning. I had a lot of trouble trying to attach the AFE cone filter to the intake. While trying to hold it in place, attach the mounting hardware, and tighten the clamp it kept slipping off. After getting someone to help hold the filter in place we finally got it to stay in place. Does the K&N filter hold on the tube better? After taking it for a drive i could,t believe the turbo whine that comes from the ASA, way more than a K&N in the swiss cheesed airbox. It sounds like a jet motor under the hood. I would strongly recommend one of these systems for anyone who likes the sound of a turbo, not to mention the cool looks of the intake and filter.
