Manley Piston Ring Set - Subaru EJ257 - WRX STI (GDB/GRF/GVF/VAB)

Manley piston ring sets for the Subaru EJ257 2.5L turbo engine in the WRX STI. Each set is made to suit Manley's forged EJ257 piston sets (632200 to 632205 series, standard and Extreme Duty), so you can order the rings that match your bore size and pistons.

Every set uses a Premium Steel top ring, a Napier-style second ring and a three-piece oil ring with tabbed rails (1.2 mm / 1.2 mm / 2.0 mm). Steel top rings are Manley's choice for high horsepower, boosted and nitrous engines. The rings are file fit, so the end gaps can be set to suit your boost and fuel.
