AWE Tuning Carbon S-FLO Intake System for G8x BMW M2 / M3 / M4

The AWE Tuning Carbon S-FLO Intake System for the G8x BMW M2, M3, and M4 addresses the flow restrictions built into the factory intake without requiring a tune or sacrificing daily usability. Built from genuine 2×2 carbon fiber with precision-machined aluminum components, the system uses AWE’s oil-less, washable S-FLO filters in an open-face airbox design that pulls fresh air from the front of the vehicle and directs intake and turbo spool sounds toward the cabin. Machined aluminum couplers provide a clean connection to the turbos and are removable for drivers planning bigger power upgrades down the line. AWE’s dyno testing on an otherwise stock G8x shows gains of 14hp and 9lb-ft of torque at the wheels, no tune required, and the system is backed by both the AWE Fitment Guarantee and No Check Engine Light Guarantee.

Massive Filter Upgrade

• Two oil-less, washable S-FLO filters sit at the heart of the system; 7-inch long by 6.75-inch wide inverted cone units with 4.5-inch outlets that increase filter surface area by 142% per filter over stock.

Designed to be Heard

• Each airbox runs an open-face design to pull fresh air from the front of the vehicle, with angled louvers built into the lids that push intake and turbo spool sounds toward the cabin while keeping engine bay heat off the filters.

Machined Aluminum Connections

• Machined aluminum couplers and spring-clamp assemblies handle the connection between the intakes and turbos, designed for a clean snap-in fit. The couplers are removable for drivers planning bigger power builds beyond factory, and threaded machined aluminum mounting posts line up with factory locations to integrate directly with the OEM inlet ducting.

Power to the Pavement

• AWE’s dyno testing on an otherwise stock G8x shows gains of 14hp and 9lb-ft of torque at the wheels. No tune required.

Fitment Guarantee

• AWE started in 1991 as an installer of aftermarket parts, which means they built the company with a clear understanding of what a poor fitment actually costs. The AWE Fitment Guarantee applies to every AWE brand product, backing the engineering with a commitment to precise fitment and clean installation by a qualified installer, without exception.

No CEL Guaranteed

• AWE’s No Check Engine Light Guarantee means no warning lights when the product is properly installed and used as intended, on a vehicle running no additional modifications beyond other compatible AWE products. Straightforward coverage, no exceptions buried in the fine print.
