AWE Tuning BMW 2021+ G8X M3/M4 S-Flo Carbon Intake

Meet the intake engineered to match the G8X’s pedigree. The S-FLO Carbon Intake combines genuine 2x2 carbon fiber construction with precision-machined aluminum components to deliver power, response, and unmistakable sound—all with factory-like fitment and zero compromise. At its core is AWE’s oil-less, washable S-FLO Filter, designed with an inverted cone to maximize flow while providing a 142% increase in filter surface area compared to stock. A massive 4.5” outlet ensures seamless breathing into the turbo, while a machined aluminum adapters ensures a perfect seal from intake to compressor. The system integrates directly with the OEM inlet ducting and retains all stock mounting points for an OE-grade install. Louvers built into the airbox are angled to direct turbo spool toward the cabin—intoxicating when under throttle, quiet when cruising. Finished in UV-stabilized resin and clear coat to maintain its finish over time, the S-FLO Carbon Intake delivers gains of +14 hp and +9 lb-ft of torque, with no tune required. It installs easily, fits like factory, and unlocks performance the way only AWE can.
