MMX Performance BMW F-Chassis N55 Oil Sump Baffle Kit
Description
The MMX Performance BMW F-Chassis N55 Oil Sump Baffle Kit is engineered as a critical reliability upgrade for enthusiasts pushing their N55-powered vehicles beyond normal driving conditions. Whether on track or during aggressive road driving, the factory oiling system can experience oil surge under high lateral and braking forces, leading to momentary oil starvation. Even brief interruptions in oil supply can result in significant engine damage, making proper oil control essential for long-term engine health.
Under hard braking and cornering, oil can shift within the sump, exposing the pickup and reducing oil pressure. The MMX baffled sump solution addresses this issue directly, utilizing advanced internal baffling and one-way oil control flaps to maintain consistent oil distribution. This results in improved oil pressure stability and significantly reduced risk of oil starvation during high-performance driving scenarios.
Manufactured from precision-machined T-6061 anodised aluminium, the MMX oil sump baffle has been developed and tested extensively through both track and road use. The design incorporates seven strategically placed one-way flaps to control oil movement within the sump, ensuring continuous oil supply to the pickup under demanding conditions. Unlike welded alternatives, this kit offers a true bolt-in installation, making it a more accessible and efficient solution for both enthusiasts and professional workshops.
