Reinforcing a Known Weak Point in the S65: MMX VANOS Covers
Owners of the E9X M3 know that the S65 V8 is one of BMW’s most celebrated engines, high-revving, naturally aspirated, and engineered for balance and precision. But even legends have their weak points. One of the most common failures on the S65 lies in the factory plastic VANOS spring covers, which can fatigue or crack over time, leading to potential internal damage and expensive repairs.
To address this, MMX has developed a direct replacement solution, precision engineered from CNC-machined 7068T aluminum to permanently eliminate the issue. This material choice offers one of the highest tensile strengths in the aluminum family, meaning it can withstand both the thermal and mechanical stresses that often lead to OEM component failure.
A Simple but Critical Upgrade
Unlike temporary fixes or full VANOS replacements, the MMX covers snap directly into place with no special tools or irreversible modifications required. Each piece mirrors the OEM form for proper fitment while vastly improving durability and heat resistance. The black anodized finish not only protects against corrosion but maintains a clean, OEM-plus look under the hood.
Designed, Tested, and Manufactured in the UK
MMX’s in-house engineering team designed and tested the VANOS covers in the UK using the same principles applied across their full S65 and S85 component lineup: precision machining, motorsport-level validation, and long-term reliability. The result is a cost-effective, permanent solution that safeguards one of the most critical systems in your S65 engine.
IND’s Perspective
At IND, we have seen firsthand how the S65’s VANOS system can turn into a costly repair for unprepared owners. The MMX covers provide the kind of preventive upgrade we always recommend, one that maintains originality while quietly improving longevity. For any E90, E92, or E93 M3 owner chasing OEM-plus reliability, this is one of those small parts that makes a big difference.
