The naturally-aspirated S85 V10 fitted to the E60 M5 was crafted by BMW using the most advanced engineering technology available to the automotive industry.

Improving upon this engine design is therefore a significant challenge.

aFe, however, has developed a clever and highly reliable method of extracting 5 hp and 6 lb/ft of torque from the engine with their Power Pulley kit - an admirable achievement.

CNC machined out of billet aluminum and black anodized for a BMW-approved appearance, the complete bolt-on kit includes the performance pulley, all bolts and new belts.
