Description
This Platinum Series piston family targets 2015+ Subaru WRX (FA20F) engine combinations and should be selected from the finished-bore specification rather than from vehicle fitment alone. The parent listing is distinguished by 86mm / 10:1, which should be cross-checked against the rest of the engine combination.
For 2015+ Subaru WRX (FA20F) builds, piston grade and bore size should be treated as measured engine-build specifications. Confirm the matching cylinder and any required piston-to-wall clearance before assembly.
