|Performance Air Filters
Changing to a sports freeflow air filter will liberate extra performance (especially when fitted in conjunction with an appropriate freeflow exhaust). Please be advised that noise generated (intake rasp) is likely to be increased over a standard item. These longlife cotton gauze or foam filter elements only require cleaning, (not replacing) at service intervals.
How to clean: immerse for several hours in a tray of petrol (agitate if in a hurry), when dry spray with any light aerosol oil.
Air Filter Nuts
Please note that any of the filters on this page can be fitted with the air filter nuts as shown further down this page.
These nuts will suit all air filters with the standard 1/4" housing thread (eg K&N, Speedograph, Arden, Continental, Webcon, Mr Gasket etc) so will replace lost housing nuts.
