aFe Power’s new power pulley brings performance engineering to your BMW M5 or M6 with the S85 V10 engine. This power pulley is a complete bolt-on kit, including the pulley, bolts, and belts. aFe’s power pulleys are CNC-machined out of billet aluminium and black anodized for that aggressive look under the M5’s bonnet. This power pulley does not modify factory harmonics or dampening.

In recent Dyno testing this power pulley produced 5 HP and 6lbs. x ft. torque.
