Mahle OE CP20 Oil Ring Expanders Set for 4.65 Inch Bore - 3.0mm Plain Rings

The Mahle OE CP20 Oil Ring Expanders are designed for high-performance engine rebuilds and repairs, offering reliable oil control for engines with a 4.65-inch bore. Crafted with precision, these expanders ensure a proper fit and optimal sealing, contributing to engine efficiency and longevity. Made by Mahle OE, a trusted name in automotive components, these rings are engineered to meet stringent quality standards and provide consistent performance. The set includes plain rings with a thickness of 3.0mm, suitable for a variety of engine applications requiring durable and dependable oil control components.

Constructed for ease of installation, these oil ring expanders feature a robust design that maintains shape and function under demanding conditions. Their compatibility with standard engine specifications makes them a versatile choice for rebuilders and mechanics seeking quality replacement parts. The rings are manufactured without carburetor approval, indicating they are intended for general automotive use and not for emissions-critical applications. As a non-CARB approved part, they are ideal for off-road, race, or vintage engine projects where compliance is not mandated.

Designed for use in engines that demand precise oil sealing, these Mahle oil ring expanders provide a seamless fit that helps prevent oil consumption and excessive blow-by. Their compact dimensions and durable construction contribute to the overall performance of the engine, ensuring smooth operation and reduced wear over time. Whether performing a complete rebuild or replacing worn components, these Mahle OE rings deliver the quality and reliability expected from a leading automotive parts manufacturer.

  • Designed for 4.65-inch bore engines for precise oil control
  • Plain rings with a thickness of 3.0mm for reliable sealing
