JR Replacement Flat Focus RS MK1

The only filters that will protect your engine against particles as small as 2.8 microns, giving 99% filtration. JR filters were founded in 1992 to develop and produce high technology air filters and are one of the few performance filter companies to be TUV approved. JR Filters are produced using 4 layers of surgical cotton, which are held together by 2 layers of steel wire mesh.

To prevent rust, they are galvanized and covered with plastic which gives double security. With these filters fitted, power is increased and fuel consumption reduced. JR Filters are TUV approved and come with a lifetime guarantee to the first owner. The filters are washable, which means they are always reusable; no more changing and no need for disposal.
