The COBB Tuning SF Intake utilizes our custom design to maintain optimal flow and net the ideal performance. The custom conical cloth filter feeds filtered air directly to the engine, while maintaining optimal intake velocity and minimizing turbulence found with many aftermarket intake systems. The COBB Tuning SF Intake system is compatible with Stage 1 and Stage 2 OTS (off the shelf mapping) provided for our AccessPORT ecu tuning device.
