I decided to do a service on a Toyota MR2 Spyder Roadster. Spark plugs were in need of replacing and replaced air filter as well. There was a definite increase of power with the K&N filter and was easy to fit. No need to modify anything, it goes straight in to air filter box. Delivery was next day.

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!
