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

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.
