Our cotton breather filters are ideal for engine breather systems, gearbox breathers or oil catch can breathers. With many modern cars, the engines are designed to return the crankcase fume back into the engine normally via the air intake system and the inlet manifold.
When this happens, the oily fumes can contaminate the air/fuel mixture. This can lead to the car running poorly, with high fuel and oil consumption as well as smoky exhausts. Our cotton breather filters are designed to release vapour into the air, rather than feeding it back into the engine system. This promotes a healthy engine, and increased performance levels.
