This Manley Performance piston ring set is engineered for Subaru EJ205 and EJ257 engines, specifically found in WRX and WRX STI models. Designed for a 92.0mm bore, these rings feature a "File Fit" design, allowing engine builders to achieve exact end-gap tolerances for optimal cylinder sealing and blow-by control in high-performance applications.

The file-fit nature ensures you can customize the gap to suit your specific boost levels and application requirements, whether for a spirited street build or a dedicated competition engine.
