Description
The MMX Performance Aluminum BMW DCT Oil Pan is a high-engineering upgrade designed to overcome the structural and thermal limitations of the factory plastic transmission sump. Developed and manufactured in the UK after extensive performance testing, this unit is precision-machined from 6061-T6 billet aluminum, delivering a significant improvement in strength, heat management, and long-term reliability for BMW dual-clutch transmission (DCT) applications.
One of the key advantages over the OEM plastic pan is its increased oil capacity of up to 1.4 liters (1.48 quarts), which enhances thermal stability and ensures more consistent lubrication under sustained load conditions. This makes it especially beneficial for spirited road driving, track use, and high-performance builds where transmission temperatures are critical.
Thermal performance is further improved through an integrated external fin design, which increases surface area and promotes more efficient heat dissipation. Internally, the pan features a purpose-built baffling system that controls fluid movement under high lateral and longitudinal forces, reducing the risk of oil starvation and ensuring stable hydraulic pressure for precise DCT clutch operation.
Unlike many aftermarket alternatives that rely on sealant-based installation methods, the MMX oil pan is supplied with an OEM-specification gasket, ensuring a clean, reliable, and direct-fit installation. It also maintains full compatibility with the factory BMW DCT filter system and allows reuse of the OEM magnet for debris collection.
For advanced applications, the design incorporates three additional -8AN ports, enabling integration of external oil cooling systems or temperature sensors. This flexibility makes it an ideal solution for motorsport, high-horsepower builds, and thermal-critical environments.
Available in clear anodized or black anodized finishes, the MMX DCT oil pan combines corrosion resistance with a refined OEM+ appearance, making it both a functional and aesthetic upgrade.
