An intake for the BMW F3x 428i that increases power, and looks good doing it. The AWE Tuning BMW F3x 428i S-FLO Carbon Intake.

The carbon fiber air box

The AWE Tuning BMW F3x 428i S-FLO Carbon Intake is a fully enclosed carbon fiber air box made from high grade UV stabilized 2x2 twill carbon fiber to reduce yellowing from under hood heat. This airbox mounts securely in the stock location and mates up to the factory air inlet pipes, perfectly. It boasts simple access for filter inspection and helps to deliver as much power as it does good looks.

The AWE Tuning ® S-FLO Filter

The included AWE Tuning ® S-FLO Filter is specifically designed to maximize airflow in the AWE Tuning ® S-FLO Carbon Intake. This increased flow unlocks impressive max gains of 16 hp and 17 ft-lbs of torque at the crank.

The carbon fiber airbox and S-FLO Filter combination makes for an easily serviceable air filter without removing the airbox. The combo produces a more aggressive intake note than stock, with a distinctive turbo spool sound, all while keeping your car operating Check Engine Light free.

What’s in the box

The AWE Tuning ® S-FLO Carbon Intake includes the carbon fiber airbox itself, the AWE Tuning ® S-FLO Filter, and all necessary mounting hardware.
