COBB Tuning Subaru WRX & STI Parts

Available product categories in the COBB Subaru WRX and STI range typically include:

• Tuning: Accessport V3 units, Accessport mounts, holsters, carry cases and protective film.
• Intake: SF intake systems and airboxes, Redline carbon fibre intakes, aluminium intake tubes and high flow air filters.
• Exhaust & turbo: cat-back exhausts, stainless steel up pipes, turbo heat shields and urethane exhaust hangers.
• Drivetrain & shifter: Stage 1 and Stage 1+ drivetrain packages, short shifters, shift plates, shifter bushings and weighted shift knobs.
• Fuel & boost: flex fuel upgrades, fuel pressure sensor kits, billet fuel line adapters and 3-port boost control solenoids.
• Engine bay & styling: charge pipe kits, radiator shrouds, alternator covers, oil caps, Redline carbon fender shrouds and intake grille scoops.

Subaru fitment is usually identified by chassis code rather than model name alone. Common codes across this range include GC8 (classic Impreza WRX/STI), GDA/GDB and GGA/GGB (2001–2007), GE/GH/GR/GV (2008–2014), VA/VAB (2015–2021) and VB/VN (2022 onwards). Some items also list related Subaru platforms such as Forester XT (SG/SH/SJ) and Liberty GT (BL/BP), or Toyota 86 (ZN6/ZN8) and BRZ (ZC6/ZD8) where the hardware is shared.

Transmission type matters for drivetrain and shifter products: check whether the listing specifies 5-speed or 6-speed, narrow or wide barrel, and manual or CVT. Accessport listings also state the model year range and, for some vehicles, whether transmission flashing is supported. Always confirm the chassis code, build year and gearbox of your car against the product title and description before ordering.

Fitment complexity varies widely. Accessport units, dash mounts and shift knobs are generally straightforward owner-level tasks, while intakes, cat-back exhausts, up pipes, charge pipes, control arms and drivetrain packages involve raising the vehicle, working with exhaust fasteners and, in some cases, draining fluids.

Installation by a professional workshop is recommended, particularly for any part affecting fuelling, boost control, exhaust or suspension. A qualified installer can also carry out a wheel alignment after suspension work and confirm that any ECU calibration is appropriate for the vehicle's specification and local fuel. Have basic metric hand tools, a torque wrench, jack stands and replacement gaskets or hardware available as required by the instructions supplied with the product.

Does the Accessport suit any WRX or STI?
No. Each Accessport listing covers specific model years and transmissions, so match the listing to your car's build year, chassis code and gearbox.

Will COBB parts fit my Forester XT or Liberty GT?
Some items list those platforms as additional fitments. Check the chassis codes in the individual product title and description.

Are these parts legal for road use in Australia?
Emissions, intake and exhaust regulations differ by state and territory. Check your local requirements before fitting any modification.
