MMX Performance BMW S58 Billet Oil Filter Housing Cap
15 IN STOCK
The MMX Performance BMW S58 Billet Oil Filter Housing Cap is a precision-engineered upgrade designed to eliminate the common failure points associated with the factory plastic oil filter housing. OEM plastic caps are prone to cracking, deformation, and inconsistent sealing during routine servicing, often resulting in oil seepage and long-term reliability concerns. The MMX billet solution provides a permanent, high-strength replacement that improves sealing integrity, durability, and service confidence.
Each housing cap is CNC-machined from a solid block of 6061-T6 aerospace-grade aluminum using advanced 5-axis machining processes. This ensures exceptional dimensional accuracy, structural integrity, and repeatable fitment. The component is then hand-finished and anodized in a Midnight Black gloss coating, providing corrosion resistance and a refined OEM+ engine bay appearance that withstands repeated heat cycles.
Beyond material strength, the MMX housing incorporates an integrated oil pressure bypass system directly into the billet design. This eliminates the need to transfer or reuse the fragile OEM plastic bypass valve, a process that frequently leads to breakage with other aftermarket solutions. The integrated design ensures consistent oil flow and pressure regulation while removing reliance on failure-prone factory components.
Installation is straightforward and is best performed during a routine oil and filter service. The MMX cap installs directly in place of the factory unit and includes a factory-specification O-ring to ensure proper sealing and leak-free operation. It is fully compatible with OEM oil filters and is optimized for use with the MMX Performance S58 oil filter, helping address the well-documented risk of factory paper filter collapse.
Designed for both daily-driven vehicles and high-performance applications, this billet oil filter housing cap is an essential upgrade for S58 owners seeking improved reliability, consistent oil system performance, and a cleaner, more durable engine bay solution.
