What Owners Say
Owners and enthusiasts consistently praise Manley pistons as well-designed 2618 forgings that rank among top-tier choices alongside CP and Wiseco, with builders noting they don't score cylinder walls—a significant advantage. Recent feedback highlights that Manley has responded to concerns about piston weight, with newer sets showing measurable improvements. The Mahle/Manley piston and rod assemblies come in roughly 46 grams lighter than OEM components per cylinder, a substantial gain for performance builds. However, several experienced builders caution that the included rings can be problematic, becoming too soft to seal properly and leading to premature oil consumption. Despite the ring concerns, Manley maintains a strong reputation in the performance community as a reliable choice for serious engine builds.
