- Constructed of CNC billet aluminum with a hard coat black anodized finish.

BMW’s are full of creature comforts. The power to run the interior accessories is produced by the pulley system in the motor. The aFe Power Pulley reduces the amount of power it takes to run these interior accessories allowing more horsepower to be used by the motor. We have seen up to 10hp and 7lbs. x ft. torque gained by these simple bolt-on products. aFe Power Pulleys are constructed from durable and lightweight CNC machined billet aluminum and are coated in a hard black anodized finish.
