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.
