BMW Engine Parts

This is a replacement set of bolts for the oil pan on your BMW equipped with an M54, N52, N54, or N55. The stock bolts are easy to strip, break, or even lose. Replace your missing or damaged bolts with all new hardware from OEM Rein to ensure a tight seal all around your oil pan and prevent oil leaks.

Check fitment with our guide above to ensure these are the oil pan bolts required for your vehicle.

Maintaining proper oil levels in your engine is crucial for peak performance. Undetected leaks can cause your oil to drop to dangerously low levels between oil changes, leading to severe engine damage.

One common culprit for oil leaks is the valve cover. Over time, exposure to extreme temperature fluctuations can wear down the gaskets, causing them to fail. Prevent oil leaks and protect your engine by replacing these vital components.

Comprehensive Kit Includes:

Valve Cover Assembly Valve Cover Gaskets Gasket Flange CCV Hose Hardware Replace your old gaskets with our high-quality kit to keep your engine running smoothly and efficiently.

Upgrade your stock oil cooler thermostat for improved performance. Swap your factory 110-degree Celsius thermostat for a new 70-degree Celsius version for faster oil flow and extended temperature control. With oil temperatures reaching 230 degrees Fahrenheit by the time your factory thermostat opens, initiating oil flow at lower temperatures proves more effective than attempting to cool down already elevated temperatures.

Utilizing a factory-style thermostat, this upgrade can be used in all weather conditions and allows your engine to warm up properly, unlike thermostat bypass kits.

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.

Perfect for DIY enthusiasts, this all-in-one kit has everything you need to refresh your ignition system! With just one click, you'll get high-quality, matching replacement parts, making it simpler than ever to service and restore your ignition system.

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's MSS65 DME uses a unique ignition system known as Ionic Current Control. 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 as a current probe, applying a low voltage to the electrode immediately after the power stroke and sending the resulting current to the Ionic Current Control Unit (ISS) for evaluation. 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 the typical Zener diode in the secondary winding, allowing for accurate current measurements without triggering fault codes in the engine control unit (DME). Bavarian Autosport ignition coils are manufactured to the exact specifications of the OE Ionic Current Control-compatible ignition coils, 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. Constructed with durable, heat-resistant plastic and featuring premium rubber spark plug boots, each boot is pre-lubricated with dielectric grease to ensure smooth installation and prevent corrosion.
