Product Description

Article Number: 13717521023

Air filter cartridge
This compact component keeps the air that is drawn into the engine parts dust- and dirt-free and ensures the engine has an adequate supply of clean air. It also regulates the temperature of the air and the crank casing ventilation, the combustion processes and the composition of the exhaust fumes.
Tailored to the engine, the air filter contains 'pockets' to maximise dust absorption for longer, an impregnated resin compound to reduce moisture absorption and maintain long-lasting engine power, and GRP casing, capable of withstanding extreme temperatures.
