Sternn,
Sorry I'm just getting back to this thread. Anyway, its just a replacement for the stock filter, I can't honestly tell you how much, if any, difference it makes, but I do like the fact that I can clean and reuse it. That and my son sure likes having his Matchbox car container K&N flitercharger equipped.
todwic,
Yeah, I know how lucky I am to have them so close. They're all great guys. Heck, I've spent entire afternoons there talking Porsche. The owner, Al Zim, has been around Porsches forever and loves to sit around and shoot the ****. If you ever need anything from them and you're not quite sure what, ask for Kirk. Not only is he a great guy but he really knows his stuff when it comes to our cars and has helped me out more than once when I was stuck.
