In order for the engine to get enough clean air, you need an air filter with a larger filter surface. Our universal air filters from BOOST products consist of a black cotton mat in a stable wire mesh. Due to the black color, the air filters are not a conspicuous splash of color in the engine compartment and are significantly less conspicuous than other products that immediately catch the eye with their striking colors. The filters are also equipped with black, flexible silicone. This makes them less sensitive to scratches or stress cracks, as is the case with rigid metal connectors. The air filters are shipped pre-oiled, washable and reusable. The washing and care products are also available from us. They are therefore more sustainable and cheaper in the long run than original paper air filters
