MMX Performance Billet Oil Filter Housing Cap - Various BMW & Toyota Models w/ B58 Engine 2017+
Lease for as low as $/week
The MMX Performance BMW B58 / B57 Billet Oil Filter Housing Cap is a precision-engineered upgrade designed to eliminate the well-documented weaknesses of the factory plastic housing. OEM plastic caps are prone to cracking, deformation, and inconsistent sealing during routine servicing, which can lead to oil seepage and long-term reliability concerns. The MMX billet solution provides a permanent, structurally robust replacement that improves sealing integrity and overall service confidence.
Machined from a solid block of 6061-T6 aerospace-grade aluminum, the MMX oil filter housing cap delivers exceptional strength while maintaining a lightweight design. The component is finished in a durable Midnight Black anodized coating, providing corrosion resistance and a refined OEM+ appearance that withstands repeated heat cycles and regular maintenance intervals.
From an engineering standpoint, the MMX housing cap incorporates a fully integrated oil pressure bypass system within the billet structure. This eliminates the need to transfer or reuse the fragile OEM plastic bypass valve, a process that often results in component damage on alternative aftermarket solutions. By integrating this function directly into the cap, MMX ensures consistent oil flow, stable pressure regulation, and long-term durability without reliance on failure-prone factory components.
Installation is straightforward and is ideally performed during a routine oil service. The 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 remains fully compatible with OEM oil filters and is optimized for use with the MMX stainless steel lifetime oil filter, providing a complete solution to address the known limitations of the B58 oil filtration system.
Designed for both daily-driven vehicles and high-performance applications, the MMX Performance Billet Oil Filter Housing Cap is a critical upgrade for owners seeking improved durability, consistent oil system performance, and a cleaner, more refined engine bay.
