Cosworth Performance Air Filters are constructed from a proprietary synthetic, non-woven single layer, pleated polyester filter media that requires no oiling. For an OE like fit, the filter housing is injection molded from High Impact Polystyrene. Each Cosworth air filter has been engineered to fit the vehicles original air box providing a true cold air supply to the engine. Cosworth Performance Air Filters also provide increased air flow when compared to the original equipment air filter.
