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 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)
