Manley 2015+ Subaru WRX FA20F 86.1mm +0.1mm Bore 10:1 Dish Piston Set of 4

Manley Platinum Series pistons deliver forged strength for 2015-2021 Subaru WRX models with the FA20F 2.0L turbo engine. This set of 4 features a 86.1mm bore size suited for +0.1mm overbore rebuilds and a dish-top design targeting 10:1 compression ratio. Engine builders choose these for handling high boost levels with proven durability in racing and street applications.

Key Features

  • 2618-T61 Forged Alloy: High-silicon aluminum construction resists detonation and withstands extreme cylinder pressures in turbocharged FA20F builds.
  • Dish Top Design: -8.5cc volume supports 10:1 compression ratio when paired with stock head gasket and milling for balanced power delivery.
  • Tool Steel Wrist Pins: Included 22mm diameter pins with wear-resistant coating ensure secure connection to rods under high-rpm stress.
  • Moly Skirt Coating: Reduces friction and galling on cylinder walls for quieter operation and longer skirt life in performance engines.
  • Optimized Skirt Profiles: Cam and barrel shapes with accumulator groove minimize blow-by and promote even ring seal across the power band.

Product Notes

  • Rings not included. order compatible 1.2mm/1.5mm/2.8mm sets for proper gap and tension.
  • Set balanced to within 1 gram. verify rod and crank balance during assembly.
  • Ships in protective foam packaging. inspect for shipping damage upon receipt.

Installation Notes

  • Professional installation recommended.
  • Hone cylinders to 86.20mm finished bore with G58 or similar hone for ideal clearance.
  • Compatible with OEM rods. use ARP rod bolts for boosted applications over 400whp.
