Process West - Subaru Liberty / Legacy GT (BL/BP)

The Liberty / Legacy GT range covers top mount intercoolers designed to sit under the bonnet scoop, cold air intakes for the factory airbox area, and silicone intercooler hose adapters used when combining Process West cooling components. Billet intake manifolds listed for EJ20/EJ25 applications also cover Liberty GT fitment alongside WRX, STI and Forester XT. For related EJ platform parts, see Process West Subaru WRX / STI (GD) and Process West Subaru Forester XT.

The turbocharged Liberty / Legacy GT sold in Australia uses the BL chassis code for the sedan and BP for the wagon, generally covering the 2004-2009 model years with the EJ20 or EJ25 turbo engine. Some Process West listings reference the model by year range (for example "Liberty GT 2004-2009") rather than the chassis code, and some multi-fit items are described by engine family (EJ20/EJ25). Confirm your chassis code, engine code and whether any previously fitted aftermarket intercooler, manifold or hoses change the required part.

Intercooler, intake and manifold work typically involves removing the bonnet scoop or airbox, disconnecting boost pipework and sensors, and refitting hoses and clamps to the correct torque. Some kits may require supporting parts such as hose adapters, silicone couplers or a compatible intake manifold, and a tune may be appropriate after induction changes. Installation by a professional workshop is recommended, and any manufacturer instructions supplied with the product should be followed.

Does BL/BP cover both body styles? Yes - BL refers to the Liberty GT sedan and BP to the wagon of the same generation.

Are some of these parts shared with the WRX? Some items, such as billet intake manifolds and certain hose adapters, are listed for multiple EJ20/EJ25 Subaru models including the Liberty GT. Check the product title for the listed applications.

Will I need a tune? Induction and intercooler changes can alter airflow, so a tune by a qualified tuner may be appropriate. Follow the manufacturer's guidance.
