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.

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.
