Proper airflow is crucial to an engine’s performance. When it comes to precisely engineered automobiles like the Porsche 981 Boxster and 981 Cayman, every bit of optimization will help you get the most from your engine. That’s why we provide these BMC F1 replacement air filters. They fit perfectly in the 981’s OEM air boxes and are built with the highest quality materials. Starting with its outer frame, BMC uses a special soft rubber material made in a process called "full molding", which not only provides a much tighter seal around the filter, but also eliminates any potential cracking or breaking of the filter. The filter element itself is made of a washable cotton material that provides nearly 40% greater airflow than paper, enclosed in an alloy mesh screen which helps the filter keep its shape and protects against larger debris and dirt. The increased flow of air through the filter provides a steady stream of clean air to the engine, resulting in much more consistent and efficient power.FEATURES:Fits all 981 Boxster/Cayman vehicles from 2013-2016Sold as a pairLifetime filter is washable and re-oilableOriginal equipment for the Ferrari Formula 1 Team and Ferrari GT race team, as well as Porsche Motorsports, Mercedes Benz F1 and GT race teams, and the AUDI Motorsports Team Track Page Views With Auctiva's FREE Counter
