N55 Baffled Sump + ACL Performance Bearings
 
Protect your N55 the right way. This N55 baffled sump paired with ACL performance bearings is a proven upgrade for anyone pushing their engine harder than stock — whether on track, spirited street driving, or high-boost builds.
The baffled sump is designed to control oil movement under hard cornering, acceleration, and braking, dramatically reducing the risk of oil starvation. This is a critical upgrade for N55 engines, especially when driven aggressively.
Paired with ACL performance bearings, this setup improves bearing durability and oil film strength compared to OEM bearings. ACL bearings are trusted worldwide for their consistent clearances, superior materials, and ability to handle increased loads and higher RPMs.
