MK4 Focus ST Panel Filter
The last Panel filter you will buy for your car!
Designed to directly replace your standard air filter element, Pipercross panel filters can be fitted in minutes for a lifetime of performance engine protection.
Pipercross air filters increase the airflow to your engine by up to 30% more than a standard paper air filter, whilst still providing superior protection from dirt and dust particles. By making changes to the Air Filter we are allowing the engine to draw air in much more efficiently, this is crucial when trying to improve the power output of the engine. The first step is done by the means of a more efficient air filter with better peak airflow.
When dirty, the filter can then be simply cleaned and refitted without the mess of other reusable air filters.
