Choosing the Right Part

Process West listings are organised by chassis code, so match your car before ordering. Subaru WRX and STI codes include GC8 (Bugeye and Blobeye bonnet scoop variants), GD (Bugeye, Blobeye, Hawkeye), GE/GH/GR/GV, GRB/GVB, VA and VB/VN. Forester XT is listed as SG and SH, and Liberty / Legacy GT as BL/BP.

Some parts depend on more than the chassis code. Verticooler brackets for the WRX GE8/GH8 are specified for the STI six-speed transmission, and certain Forester XT SG top mount kits are made for cars running an 02 STI bonnet scoop. Ranger Raptor P703 piping kits note Stage 2 intercooler compatibility.

Cold air intakes are offered in different pipe sizes, including 72mm versions, and some use K&N filtration. Billet intake manifolds for EJ20/EJ25 engines suit WRX, STI, Forester XT and Liberty GT, with some variants including additional bungs for port injection. If you run port injection or E85, confirm the manifold variant first. Colour options such as black are listed where available.

Installation & What You'll Need

Installation by a professional is recommended for all Process West cooling and induction products.

Many Process West front mount intercooler kits are designed as no-cut fitments that sit behind the factory bumper without trimming the bar or bumper support. Always check the individual kit description against your model year, as bumper and headlight variations across WRX VA and VB can affect intercooler pipe routing.

Verticooler and top mount kits bolt into the factory top mount location on most WRX and Forester XT applications, but require removal of the standard top mount piping, so allow more workshop time than a straightforward intake swap.

Billet intake manifolds on turbocharged Subarus generally require a matching tune to realise the benefit of the improved flow. We don't quote boost or power figures here, as results depend on your engine, turbo and tune combination — refer to the figures Process West publishes for your setup.

FAQ

Where can I buy Process West intercoolers in Australia?
Chicane Australia stocks Process West intercoolers, intakes and intake manifolds and ships Australia-wide from the NSW Central Coast. Shop by vehicle above, search by Process West part number, or contact our team with your chassis code.

What makes the Verticooler different from a standard top mount?
The Verticooler tilts the core so hot air has a clear path down and out of the engine bay, rather than pooling around the intake as it can with a conventional top mount.

Do I need to cut my bumper to fit a Process West FMIC?
Many kits are designed to fit behind the factory bumper with no cutting required. Check the specific listing for your model, as bumper and bar variations between years can change what's involved.

Will a billet intake manifold need a tune?
On most turbocharged Subarus, yes. The change in flow affects how the engine breathes, so a matching tune is recommended to get the benefit of the manifold.

Does Process West only make parts for Subaru?
No. Alongside the Subaru range there are products for the Ford Ranger Raptor P703 and Falcon BA/BF, plus Terratuff by Process West items for the Toyota HiLux N70 and N80 and Holden Colorado RG.
