Product Details
This is a Manley Piston Ring set designed for Subaru EJ205WRX and EJ257 WRX STi engines with a 100mm bore. These rings are a file-fit style, meaning you'll need to gap them to your specific piston and cylinder wall clearance during installation. The ring dimensions are 1.2mm for the top ring, 1.2mm for the second ring, and 2.0mm for the oil ring.
When you're rebuilding the top end of your Subaru's engine, getting the right piston rings is crucial for proper sealing and compression. Manley is a well-known name in performance engine components, and this set is built to meet the demands of these turbocharged boxer engines. The file-fit design gives experienced builders the flexibility to achieve precise ring gaps, which is important for optimizing performance and durability in high-stress applications.
Keep in mind that this ring set is not CARB approved and cannot be shipped to California. Always refer to your engine's service manual for the correct installation procedures and ring gapping specifications.
