The K&N Air Filter that I recently purchased for my 2004 Toyota Celica GT has been an incredible upgrade! Since the K&N upgrade my Celica GT has gained improvements in both acceleration, and over all gas mileage! Also, judging by both sound & feel the engine is without question running the way it was intended! Thank you K&N for making such an amazing product!

Works great. I haven't driven the car much since I'm still getting it up to snuff. It was neglected for many years before I bought it. Car (1990 Audi 200 quattro turbo) pulls a little harder now but I bought it mostly for ease of cleaning and the infrequent cleaning intervals. These cars have a difficult-to-reach airbox.
