This drop-in air filter kit replaces the OEM paper elements with multi layered cotton filters that flow 18.6% more than stock (1022 CFM versus 862 CFM per bank at 28 inches of water). It fits both the factory F97 X3M / F98 X4M airbox and the Dinan High Flow Carbon Fiber Intake (D760-0054), delivering gains of up to 7 wheel horsepower and 8 lb-ft of torque at 4750 rpm. Steel wire mesh backing adds strength and dent resistance across the full set of four filters.
