What Owners Say
Owners and enthusiasts consistently praise Manley pistons as well-designed 2618 forgings that rank alongside top brands like CP and Wiseco, with many builders preferring them for serious engine builds. The pistons earn specific recognition for not scoring cylinder walls and for their reduced weight compared to OEM components—up to 46 grams lighter per assembly in some applications, which is significant for performance builds. However, some users report that the included piston rings can become too soft over time, leading to premature oil consumption and sealing issues. Despite this ring concern, Manley has shown responsiveness to builder feedback, addressing earlier complaints about excessive weight. The brand maintains a strong reputation among performance engine builders for quality forgings and continuous product improvement.
