CP Shelf Pistons for Subaru EJ257 WRX Sti Stroker

The CP Shelf Pistons, designed specifically for the Subaru EJ257 WRX Sti Stroker, are engineered to deliver exceptional performance and durability. These pistons are crafted with precision and incorporate several advanced features that set them apart. The set includes pistons, pins, rings, and locks, ensuring a complete package for your engine's needs.

Advanced Piston Features

These pistons are equipped with Anti Detonation Grooves, also known as Contact Reduction Grooves, which protect the top ring and limit piston/cylinder contact during high temperature and RPM. This feature helps prevent detonation and maintains optimal engine performance. Additionally, the Accumulator Groove collects excess blow-by, enhancing ring seal and reducing top ring flutter. The Constant Pressure Groove, or CP groove, ensures a uniform pressure distribution, which, when combined with lateral gas ports, keeps the gas ports clear of carbon buildup and prevents smudging.

Performance and Durability

The X-Forgings used in these pistons minimize friction and reduce weight, while maintaining strength. The Radius Domes maximize quenching and eliminate hot spots that can lead to detonation. The cam and barrel design, the result of extensive research and development, promotes tighter clearances, less noise, better ring seal, more power, and increased durability. Whether for daily driving or high-performance applications, these CP Shelf Pistons are the ideal choice for those seeking top-tier performance and reliability.
