From the factory, BMW S65 valve cover bolts feature integrated non-serviceable grommets. These rubber seals tend to weaken, becoming brittle after years of heat and oil exposure. Replacing these bolts and integrated grommets can total over $280

To address this issue, NRW has developed a solution: a silicone replica of the factory rubber grommet, boasting a superior heat resistance of 170 degrees Celsius compared to the original's 120 degrees Celsius. Each kit contains 26 grommets, enough to service both valve covers.

Free additional power to your M3’s rear wheels without sacrificing or compromising your BMW’s reliability. Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance. Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in an additional 9-14 HP and 7-9ft. lbs TQ gain for the M3. Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. All factory harmonics/balancing are undisturbed. Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and comes fully equipped with new belts. Already have this kit and need new belts? See T#14491 and T#14489 Performance Underdrive Pulleys Features: DualDrive design allows maximum performance, with minor effect on accessory speed Proper cooling temperatures are retained at proper levels on or off the track Maintains proper alternator speed, allowing sustained levels to sensitive control modules Machined from 6061-T6 aerospace aluminum T3 Hard-Anodized for maximum strength and corrosion/wear resistance No affects to crankshaft dampening or harmonics Simple bolt-on installation

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent. The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories. These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Introducing NRW Design's Aluminum S65 Valve Covers – a game-changing solution meticulously crafted to address the persistent challenges associated with factory S65 valve covers. These innovative valve covers have been engineered to set new standards in performance, durability, and aesthetics, making them the ideal choice for BMW enthusiasts. The Problem: Factory S65 valve covers, made from magnesium alloy, suffer from micro porosity and corrosion over time. This leads to the development of unsightly surface "pimples," leaks, and accelerated oxidation. These issues commonly affect gasket channels and edges, resulting in persistent oil leaks that can't be easily resolved by conventional means. The Solution: NRW Design presents a revolutionary answer with the first and only true 1:1 design aluminum valve cover for the BMW S65 engine. Our valve covers have been meticulously designed to eliminate the shortcomings of factory covers, offering a range of unprecedented benefits. Key Benefits: Corrosion-Resistant Aluminum: Unlike magnesium, aluminum is immune to micro porosity, ensuring there's no room for oxidation or corrosion. Aluminum valve covers have a proven track record across various models and manufacturers. True-to-Design Replication: The NRW Design valve covers are faithful reproductions of the original S65 valve covers. Every existing component – from gaskets, bolts, and sensors to caps, plug tubes, separators, and coil packs – fits seamlessly without requiring modifications. Customizable Powder-Coating: Enjoy the freedom to select from a variety of colors and finishes to match your personal style and preferences. Cost-Effective Solution: NRW Design valve covers offer a cost-effective alternative to the original BMW valve covers, delivering exceptional value without compromising on quality. Unmatched Longevity: These valve covers are die-cast from A383 alloy, chosen for its exceptional properties, ensuring unparalleled longevity and stability. Engineered for Performance: NRW Design meticulously retained critical features of the original design, including the high-pressure hump near oil separators, ensuring optimal pressure control and effective oil management. Stringent Quality Control: Each valve cover undergoes rigorous quality checks throughout the manufacturing process, ensuring precision and reliability at every step. Limited Lifetime Warranty: NRW proudly stands behind the quality of their products, supporting it with a lifetime replacement from fit and function.

Free Up Real S65 Power — Engineered the Turner Way Your S65 is already making the power. This kit simply lets you keep more of it. The Active Autowerke Power Pulley Kit for the BMW E9X M3 reduces parasitic drag at the crankshaft, trimming rotational mass and freeing up horsepower that would otherwise be consumed by accessory drive load. The result is a measurable increase in rear-wheel output without sacrificing the balance, cooling capacity, or long-term durability expected from a properly engineered BMW upgrade. The crank pulley is CNC-machined from billet 6061 aluminum and finished with a hard-coat anodize for durability under sustained high-RPM operation. Unlike undersized pulleys that compromise system function, this design maintains proper operating characteristics while delivering real-world gains. Late-2007 production E9X M3 models transitioned to a double-sided (DPK) A/C belt configuration. Rather than forcing a workaround, Active Autowerke developed a proper DPK-compatible solution — including the correct matched belt. Applicable kits also include a spare DPK belt for added insurance. Dyno testing on a Mustang chassis dyno confirms gains of 10–12+ rear-wheel horsepower on an otherwise stock vehicle. Installation is fully reversible and requires no permanent modification. Product Highlights 10–12+ RWHP gain verified on stock S65 engines Complete bolt-on system CNC-machined 6061 billet aluminum crank pulley Hard-coat anodized finish for durability Includes correct replacement drive and A/C belts Spare DPK belt included where applicable Compatible with manual and DCT-equipped E9X M3 Reduces parasitic drag and rotational mass Designed to maintain proper operating temperatures Works in conjunction with Active Autowerke performance software Available for single-sided and double-sided (DPK) belt configurations Fitment Information Confirm whether your E9X M3 is equipped with a single-sided or double-sided (DPK) A/C belt prior to ordering to ensure correct application. A properly engineered solution for enthusiasts who want measurable gains while preserving OEM-level refinement and reliability.
