Subaru WRX Engine Piston - Manley Performance - 86.1mm +0.1mm Bore 10:1 Dish (2015–2027). A forged single piston for the FA20F, built for reliable power and ring seal in performance builds.
Made from domestic 2618 forged aluminum, this Manley piston uses cam and barrel skirt profiles and exacting ring lands and grooves for consistent sealing under boost. Unique fixturing machines the skirt and ring grooves in one operation for precise groove-to-skirt squareness. The 86.1mm (+0.1mm) oversize suits a cleanup hone, while the 10:1 dish preserves efficient combustion for responsive street or track use. Proven by professional engine builders, it’s a strong foundation for your WRX project.
