Thomas Theilmann, Monroe, North Carolina
Great fit, could hear and feel a positive difference immediately.
Garcia, Surrey, United Kingdom
Easy to fit, easy to clean, even the engine sound is a bit better, and the petrol consumption is less than with the original filter. Highly recommended.
Lee Lovatt, Muskegon, Michigan
Easy to install of course...exhaust sounds more throaty. Power increase is notable. Fuel economy, 5 extra mpg. Worth every penny.
