Description
Unlock the full potential of your BMW E9X M3's S65 V8 engine with the Active Autowerke Power Pulley Kit. Designed to free up additional horsepower through a redesign of the crankshaft outer pulley, this kit delivers measurable power gains without compromising reliability. Engineered from aircraft-grade billet 6061 hard coat anodized aluminum, this kit provides exceptional strength and durability while maintaining a factory-like look with its sleek, jet-black finish.
One of the unique features of this kit is its inclusion of a specially designed double-sided A/C belt (DPK), a first in the BMW aftermarket performance industry. Active Autowerke has gone above and beyond by providing an additional spare DPK belt for emergency situations, ensuring you’re always prepared. With a fully reversible design, this bolt-on upgrade is easy to install and enhances your driving experience with minimal effort.
Dyno-tested to deliver 12+ horsepower on a stock M3, this Power Pulley Kit is the ultimate upgrade for any BMW enthusiast looking to enhance performance while maintaining the inherent qualities of the BMW E9X M3.

Note: To determine if your M3 has a DPK or single-sided belt:
- If the A/C belt has grooves on both sides, it is a DPK belt (models produced from 06/2008 onwards).
- If the A/C belt only has grooves on one side, it is a single-sided belt (models produced up to 05/2008).
