BMC F1 Replacement Air Filter

BMC F1 replacement air filter for the Porsche 718 Boxster and Cayman Base/S (2017+), a drop-in fit for the factory airbox in place of the OEM paper element. BMC's full-molded soft rubber outer frame seals tighter than stock and resists cracking, while the washable cotton filter element in an alloy mesh screen flows nearly 40% more air than paper for a steadier, more consistent supply of clean air to the engine. Carries a 98.5% filtering efficiency rating to ISO 5011, and the filter is washable and re-oilable for the life of the car.
