aFe Power's new power pulley brings performance engineering to your BMW M3. This 4.124" diameter power pulley is a complete bolt-on kit, including the pulley, bolts, and belts. aFe's power pulleys are CNC machined out of billet aluminum and black anodized for that aggressive look under the M3's hood. This power pulley does not modify factory harmonics or dampening. In recent Dyno testing this power pulley produced 10 HP and 7lbs. x ft. torque. aFe's power pulley fits up to production date May 2008. When it comes to engineering for power, performance, protection and value, aFe Power is the only choice. New belts included.
