On KTM ENDURO 690 from 2008 to 2018, the TWIN AIR 158421 air filter fits in place of the original part. Off-road, the engine breathes air full of dust. The oil-soaked foam filter traps the particles; worn or badly fitted, it lets through dirt that wears out pistons and cylinders.
Clean and oil the filter after every dusty ride, and at least at the intervals given in the manual; replace it as soon as the foam hardens, tears or comes away from the frame. With two filters, you always have a clean one ready to go.
Twin Air, a Dutch brand founded in 1972, makes foam air filters and intake accessories for off-road riding. According to the brand, its filters are chosen as original equipment by more than 30 manufacturers.
Does it need oiling before it's fitted for the first time?
Yes, unless it's sold pre-oiled: a dry foam filter lets dust through.
