The factory magnesium valve covers on the S65 engine are known for developing micro-porosity, corrosion, and persistent oil leaks over time. This material is highly susceptible to oxidation, leading to unsightly surface imperfections, weakened gasket channels, and sealing issues that a simple gasket replacement won't fix.

Upgrade to this high-strength aluminum valve cover set, engineered as a direct-fit replacement for your aging OEM covers. Unlike magnesium, aircraft-grade aluminum offers superior durability, enhanced heat resistance, and complete immunity to the corrosion issues that plague factory covers. Whether you're refreshing a high-mileage M3 or seeking long-term reliability, this upgrade ensures a leak-free, worry-free solution for your S65.

Maintaining optimal engine oil levels is crucial for peak performance in your BMW. Leaks can occur between oil change intervals, leading to dangerously low oil levels. The valve cover is a frequent culprit for such leaks due to gasket degradation from years of exposure to temperature fluctuations. Replace your valve cover to ensure the retention of engine oil within your vehicle.

Key benefits of replacing the valve cover include:

• Preventing oil leaks that could lead to low oil levels.
• Preserving engine performance and longevity.
• Avoiding potential engine damage from insufficient oil.

Ensure your BMW's engine operates smoothly by replacing the valve cover to contain the engine oil effectively.

Upgrade your BMW's engine bay with the Aluminum Valve Cover 11127552281M to eliminate leaks and add a touch of style. This high-quality valve cover ensures a secure seal, preventing leaks and enhancing the aesthetic appeal of your BMW.

• Aluminum Valve Cover for BMW
• Eliminates leaks for improved engine performance
• Adds style to the engine bay

If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On older BMWs, the engine ground strap is a thin, non-insulated cable that spans from the engine mount arm to the frame horn. Despite the seemingly simple nature of this part, on older cars, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.

To solve this issue, ECS has engineered an exact-fit, upgraded ground strap for your BMW! Unlike its OEM counterpart, this design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.

Whether you're replacing a visibly corroded strap or proactively preventing failure, this solution from ECS is sure to provide lasting performance and protection.

If you're noticing misfires, poor fuel economy, reduced engine performance, or ignition-related diagnostic trouble codes (DTCs), a failing ignition coil is likely the cause. Late-model BMWs, such as the E60 M5, E63 M6, and E64 M6, use a coil-on-plug ignition system, where each cylinder has its own coil and spark plug for efficient ignition. When a coil fails, the affected cylinder won't receive a spark and will misfire. Even if the misfire doesn’t trigger a DTC, you’ll still feel the difference in engine performance—rough idling, hesitation during acceleration, or a strong fuel smell. To avoid these issues, we recommend replacing your ignition coils every 40,000-60,000 miles.

The S85 engine uses a specialized ignition system called Ionic Current Control, which differs from traditional knock sensors. BMW engineers developed this system to more accurately detect pre-ignition and misfires in the high-revving, ten-cylinder S85. Instead of relying on conventional knock sensors, the system uses each spark plug to measure current after the power stroke, transmitting that data to the Ionic Current Control Unit (ICC). This allows for precise monitoring of combustion events. To support this, the S85’s ignition coils are specially designed with a modified “pencil” shape and lack a Zener diode in the secondary winding, allowing for accurate current measurements without triggering fault codes in the engine control unit (DME). These ignition coils are manufactured to the exact specifications of the OE Ionic Current Control-compatible ignition coil, and will not trigger ignition-related fault codes in the DME.

Bavarian Autosport ignition coils are engineered for reliability, delivering a consistent, long-lasting spark. These high-quality OE replacement coils are specifically designed for your S85-powered E60 M5, E63 M6, or E64 M6.

This replacement gasket from Elring is perfect to prevent any further oil leaks.

Includes the following Seals:

• Valve cover gasket
• Spark plug seals

The N54 suffers from a weak point in its crankshaft. It has been reported that when increasing the power to the engine, the crank hub can move or spin slightly under an extreme load. This is most apparent under high-rev downshifts or in the case of increased boost pressure which creates more stress on the engines rotating assembly. In order to keep this from happening, the crank bolt must be secured to the hub to keep it from backing off, but this can be a tricky solution since a simple dab of Loctite will not suffice. 

Here is an easy, and cost-effective way to secure the situation; The VTT N54 crank bolt capture. This lightweight and durable ring slips over the head of the crank bolt fully encapsulating it, and locks it to the crank hub and eliminating its ability to spin. The VTT-CBC is 100% Billet Aircraft Grade Aluminum, Anodized black to protect it from the elements, and give it a stealth look. What's more is that it weighs only 1.3 Oz's meaning you aren't adding excess mass to the crankshaft which will avoid any imbalance or vibration issues.

While this is not a full fix for all crank hub spinning issues, the engineers at Vargas have found most issues have stemmed from the bolt itself backing out, and this is a great way to keep that from happening. Extremely lightweight at only 1.3 Oz's it adds virtually no weight to the crank which is important for balance and vibration.

Kit Includes:

• 1x Aluminum Crank Bolt Capture
• 8x Fasteners Gr. 12.9
