MMX Oil Filter Housing For BMW N54, N55, S55 Engines & more

The MMX Oil Filter Housing is a premium replacement for BMW’s factory plastic housing, which is prone to cracking and oil leaks. Designed for engines including the N20, N52, N54, N55, and S55, this billet aluminium housing eliminates one of the most common weak points in BMW engines while adding strength, reliability, and style.

Each housing is CNC-machined from a single billet of 6061 aerospace-grade aluminium using advanced 5-axis technology. After machining, it is polished and gloss-black anodised for a sleek, durable finish that resists corrosion and maintains its appearance for years to come. Lightweight yet extremely strong, the MMX housing is built to last the lifetime of your car.

Unlike other aftermarket options, the MMX unit features an integrated pressure control oil bypass, meaning you don’t need to reuse or transfer the fragile OE plastic bypass valve. This ensures easy installation and improved reliability straight out of the box.
