I've been using K&N's on my performance cars since 1984. I've found them all to be of high quality and they have added noticable power. I had one in my 96 Taurus SHO deteriorate at the rubber edges, after over ten years of service. k&N replaced it for free. Can't beat that. All three of my present cars have them installed. They are a good, reliable product with a real lifetime warranty.
