BMC Performance Replacement Air Filters guarantee a superior air capacity to that of traditional paper or foam filters, ensuring a minimum loss of power in airflow and therefore obtaining a better performance from the engine. Having won numerous championships in Formula 1 and World Superbikes, their experience gained in competition is used to create BMC performance replacement elements for production vehicles, using the same technology, materials and manufacturing processes.Increased Horsepower/Throttle ResponseThe filtration material is composed of special cotton gauze soaked with low viscosity oil and covered with alloy mesh, which has an epoxy coating to ensure protection from petrol fumes and oxidisation due to humidity in the airWashable/Re-UsableThe cotton gauze has the advantage of being washable and therefore reusable, making BMC air filters excellent value for money as they can be used, cleaned and re-used over and over again!Superior Quality/FitAll BMC filters are made from hard ABS plastic in one single piece with no welded joints. This technique gives the air filter rigidity, ensuring a perfect seal, easy fitting and avoids splitting or breakage (unlike other rubber chassis filters).
