Subaru Impreza WRX STI GV Performance Parts & Upgrades

The Subaru Impreza WRX STI (GV sedan) was sold new in Australia from 2010 to 2014, with the 2.5L EJ257 turbo boxer four and all-wheel drive. It shares its running gear with the GR STI hatch, and many parts also fit the GE and GH WRX. This page lists the parts we stock for the GV STI, from COBB Accessports, intakes, intercoolers and suspension to Perrin and GrimmSpeed engine bay parts, KORSH and AWE exhausts, HARDRACE bushes and mounts, Paragon brakes and APR carbon aero.

Popular upgrades for the GV STI
  • Tuning and intake: COBB Accessport V3 (Australian spec), COBB and aFe intakes, boost control parts and flex fuel kits.
  • Turbo and exhaust: COBB x KORSH engine-back packages, AWE exhausts and conversion kits, GrimmSpeed up pipes and Turbosmart blow off valves.
  • Fuel and cooling: COBB fuel rails, pumps and regulators, Radium fuel hangers, COBB and Process West intercoolers, and COBB CSF and KOYORAD radiators.
  • Suspension: AST coilovers and camber tops, COBB sway bars, end links and toe arms, and HARDRACE and Perrin bushes and mounts.
  • Brakes and driveline: Alcon and Paragon brakes, GrimmSpeed and GFB short shifters and Drive Shaft Shop driveshafts.
  • Aero: APR carbon splitters, wings, mirrors and brake cooling plates.
Choosing the Right Part
  • Sedan or hatch: the GV sedan and GR hatch share most parts, but wings and rear aero are body-specific. APR's STI wing is listed for 2011-2014 sedans.
  • STI or WRX: the STI has the EJ257, a 6-speed gearbox and Brembo brakes. Many WRX (GE/GH) parts fit, but check engine, brake and driveline parts.
  • Tune: intake, exhaust and fuel upgrades need a tune. The COBB Accessport listed here is the Australian-spec version.
Installation

Have a qualified workshop fit suspension, brake, fuel and engine parts. Get a wheel alignment after any suspension change, and bleed and road-test the brakes after brake work. Intake, exhaust and fuel changes need a tune, such as a COBB Accessport map; ask us if you're unsure.
