Dinan Underdrive Pulley Kit for BMW M3 E9X - E90 E92 E93 - after May 2008 build
Unlock free horsepower and sharper performance with the Dinan Underdrive Pulley Kit for BMW M3 E9X. This performance pulley kit reduces parasitic drag by slowing the accessory drive of the alternator, water pump and A/C compressor, helping your engine deliver more of its power to the wheels. Engineered by Dinan and hot weather tested for reliability, it is a proven, safe upgrade for daily road use and spirited driving alike.
The pulley is manufactured from aircraft quality 6061 aluminium and finished in a durable black anodised coating. Crucially, it retains the factory harmonic damper and does not modify it, unlike some underdrive pulley kits that can be harmful to your engine. The result is a quality-built, reliable performance upgrade with real-world benefits and OEM-level refinement.
