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.

Features:

Eliminates the common porosity and corrosion issues found in factory magnesium covers.

Helps maintain optimal engine temperatures and enhances long-term reliability.

Designed for an OEM-like installation without modifications.

Reduces the risk of oil leaks, ensuring a proper seal.

Resistant to oxidation and chemical exposure for a long-lasting clean look.

This low-pressure fuel sensor is commonly a cause of an "Increased Emissions" warning on the idrive and for check engine (SES) lights on BMW's with the N54 6 cylinder turbo engine or the S65 V8 engine in the M3. It will also fit a limited number of cars with the N55 engine. This sensor can be traced to a number of drivability issues, including cold start running problems, misfires, stumbling, hesitations, and overall rough running. You will likely have a code for the misfires, rich condition, or for the sensor itself. In some cases, the combination of codes can bring about a limp mode. Replacing this sensor is an easy and inexpensive first step if you're having any of these issues. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
