Sitting in the airbox, the filter catches dust, sand and mud before they reach the carburettor or injection, and then the cylinder.

Why a foam air filter?

The foam traps dust throughout its thickness thanks to the special oil it is soaked in, while letting plenty of air through.

• Excellent airflow for the engine, even as the filter starts to load up.
• Washable and reusable many times: far cheaper than a disposable filter.
• Limit: it must be cleaned and oiled regularly, after every dusty ride; badly oiled or damaged, it lets dust through – the main cause of engine wear.

Why choose TWIN AIR?

Twin Air invented the dual-layer foam filter in 1972 and is original equipment for more than 30 manufacturers: fine filtration, washable and reusable.

When should you replace the air filter?

Replace the filter as soon as the foam is torn, hardened or coming away from its frame: dust that gets through wears the piston and cylinder in a few hours.
