Billet Aluminium Oil Filter Housing Cap for BMW B46 / B48 / N47 / N57

RTMG Performance introduces a solution to a critical engine component. Manufacturers often use cost-effective materials like ABS plastic, which over time degrades and deforms under high temperatures and pressures. The oil filter cap is one such example.

Our company has designed a BILLET aluminum oil filter cap, resistant to polymerization and deformation under extreme conditions, preventing oil leaks and failures, particularly in racing applications. In motorsport, where oil pressure is significantly increased (up to 15 bar), this product ensures reliability and performance.

Beyond its mechanical superiority, the cap enhances the engine's aesthetics, catering to enthusiasts who value both function and style. The cap features a 27mm hexagonal design on its top, allowing for easy filter replacement without specialized tools. It retains compatibility with the OEM oil filter and O-ring, ensuring a perfect fit and leak prevention.

To enhance durability, we apply a special electrochemical coating that resists oxidation and increases surface hardness, offering long-term protection and functionality.

Welcome to our team, where a new dimension of reliable performance enhancement begins!
