Racingline Performance High-Flow Replacement Filters - Audi TT (Mk3)
One of the most cost-effective improvements you can make to your car, improving power and economy. The Racingline Performance Panel Filter simply fits directly into the airbox as a direct replacement for the standard restrictive paper air filter element.
Great filter, my car feels like its breathing properly and the response on the accelerator is instant and only takes a few minutes to fit, just a straight swap.
