Green Filter Ford Focus RS/ST MK3

The GREEN-FILTER sports air filter (air filter insert) is simply exchanged for the original air filter insert in the air filter box / air box. This brings deep breathing for the engine with up to 40% more air throughput and accelerates the air flow in the intake system.

The cotton filters are insensitive to temperature and moisture. Simply wash out with the cleaning kit at the required air filter replacement interval. GREEN air filter cartridges are delivered ready to install and last a lifetime. Registration free!

Suitable for:
