My Mercedes Benz C300 is sucking air like never before. Highly recommended :)

Great product, fast well packaged delivery, which was included in the price. Perfect fit for my Bmw 540 and I can feel the difference, not massive but there is only a limit on how much it can improve - acceleration is just that little bit sharper. Would definatly buy another one when required.

Great product. I added a Remus slip on, K&N and Booster Plug to my BMW R1200RS and increased acceleration and mpg.
