Subaru WRX STI (VA) 2014–2021 Performance Parts & Upgrades

The Subaru WRX STI (VA) was sold in Australia from 2014 to 2021, with the 2.5L EJ257 turbocharged flat-four, a six-speed manual and all-wheel drive. It shares its body and much of its chassis with the WRX (VA), but the engine, gearbox and driveline are different. This page lists the parts we stock for the VA STI, including COBB Accessports, intercoolers and exhausts, Perrin and GrimmSpeed engine parts, HARDRACE suspension, APR carbon aero, GSC Power-Division and Manley engine internals, KORSH exhausts and Alcon and Paragon brakes.

Popular upgrades for the VA STI
  • Tuning and fuel: COBB Accessport V3 in Australian spec, flex fuel kits, MAP sensors, fuel rail line kits and fuel pressure regulators.
  • Intake and turbo: COBB and aFe intakes, Perrin intake tubes and bypass valves, COBB front mount intercoolers, and GFB and Turbosmart blow-off valves.
  • Exhaust: COBB, KORSH and AWE cat-backs and exhaust packages, KORSH downpipes and Perrin axle-backs.
  • Suspension: AST coilovers, COBB adjustable sway bars, alignment and roll centre kits, plus HARDRACE and SPL arms and bushings.
  • Brakes: Alcon front big brake kits, Paragon rotors and Frenkit caliper rebuild kits.
  • Engine and aero: Manley and CP pistons, ACL bearings, GSC valvetrain parts, ARP studs and APR carbon wings, canards and lips.
Choosing the Right Part
  • STI or WRX: the VA WRX uses the FA20 engine, so engine, intake, turbo and exhaust parts made for the STI's EJ257 won't fit it. Many suspension and aero parts are shared.
  • Pre-facelift or facelift: some aero parts, such as APR's front air dam and canards, are made for 2015-2017 bumpers only, so check the years in the title.
  • Wheel fitment: the VA STI uses 5x114.3 hubs, so check the stud pattern on wheel spacers and wheels.
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, turbo and fuel upgrades need a tune to suit; ask us if you're unsure.
