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.
