Product Details
Mahle is a well-known name in the engine parts world, often supplying parts for original equipment manufacturers. This specific set of piston rings, part number 4045MS-112, is a file-fit ring set designed for builders who need precise control over their engine's top end. These rings are intended for use in custom engine builds where standard rings might not offer the exact clearance needed for optimal performance and sealing.
This set features a 1.0mm top ring, a 1.0mm second ring, and a 2.0mm oil ring. The file-fit design means you'll need to carefully file the end gap of the rings to achieve the correct clearance for your specific piston and cylinder bore. This level of adjustability is crucial for high-performance or modified engines where bore sizes can vary or specific ring gap tolerances are required. It's important to note that these rings are not CARB approved and cannot be shipped to California.
