Product Details

Easy to install - reduces parasitic losses from belt driven auxiliary components. Engine crankshaft pulley remains the same, this modification simply unleashes untapped potential from your vehicle. Expect to see gains around 10 RWHP from your S65. All BMW power pulleys included, including alternator, water pump, and power steering pulleys.

Another key element in developing this under-drive pulley system was the task of manufacturing a DPK, a double side belt for the air conditioner. When you alter the crankshaft main pulley size, it also influences the size of the A/C belt.  As of late production 2007, BMW changed over the belt configuration to a double sided groove belt on the E9X M3. Active Autowerke philosophy is always to try and maintain components consistent with BMW quality. This is the first aftermarket DPK produced -  Active Autowerke will provide an extra spare DPK belt with the kit for emergency circumstances
