About this part

Product Details

The 1.2mm x 1.5mm x 3.0mm ring dimensions on this Manley Piston Ring set are specifically chosen to work with 86.25mm bore pistons, commonly found in Subaru FA20 engines. These rings are crucial for creating a tight seal between the piston and cylinder wall. This seal is what keeps combustion pressure where it belongs, pushing the piston down, and also prevents oil from getting into the combustion chamber where it would burn and cause issues.

Manley Performance has a reputation for well-built engine components, and this ring set is no exception. They are designed to handle the demands of performance engines, ensuring consistent compression and oil control. When you're rebuilding the top end of your Subaru FA20, using a matched set like this helps ensure everything works together properly for optimal engine performance and longevity.

Keep in mind that this specific ring set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
