For the Falcon owner who refuses to compromise, the Process West Stage 3 Performance Package represents the ultimate cooling and induction setup available for the FG platform.

This is not just an upgrade; it is a complete re-engineering of the front-end architecture to support the highest horsepower builds in the country.

By combining our legendary Stage 3 "Full-Face" Intercooler with the high-flow Race Air Box and Battery Relocation Kit, this package provides the thermal overhead required for elite-level drag, roll racing, and high-boost street applications.

What’s Included in the Stage 3 Package?

1. Stage 3 "Extreme" Intercooler Kit
This kit utilises our world-renowned BA/BF Stage 3 core, re-engineered with custom end tanks specifically for the FG chassis.

The Largest on the Market: A staggering 500mm wide x 425mm high x 100mm thick bar and plate core. This is the largest and most thermally efficient intercooler available for the FG Falcon.

Optimised Piping: The kit includes a specialized 2.5-inch hot side and a massive 3-inch cold side piping system.

High-Flow Cast Elbow: Features a new 3-inch high-flow cast aluminium elbow at the throttle body to eliminate the final restriction point in the charge-air path.

2. Battery Relocation Kit
To accommodate the massive Stage 3 cooling hardware and the high-volume Race Air Box, the battery is relocated to maximize engine bay real estate.

Clean Integration: Moves the battery to the passenger side with a CNC laser-cut tray for a factory-quality finish.

Full Wiring Kit: Supplied with high-quality, heavy-duty cables and all necessary fittings for a hassle-free, 45-minute installation.

3. Your Choice: 4-Inch Race Air Box Kit
Designed to support 500rwkW+, this air box utilizes the space created by the battery relocation to house a massive 6-inch internal diameter K&N pod filter and a 4-inch bell mouth.

Select the version that matches your turbocharger's compressor inlet:

Option A: Standard 3" Turbo Inlet
Ideal for those running the factory turbocharger or aftermarket units with a 3-inch inlet. This version includes a wire-reinforced silicone hose that transitions from the 4-inch airbox down to the 3-inch turbo.

Option B: 4" Turbo Inlet
Designed for high-output builds featuring upgraded turbos (0.7A/R cover) with a 4-inch inlet. This version provides a straight 4-inch to 4-inch silicone hose for the shortest, most direct airflow possible.

Why Choose the Stage 3 Package?
The Stage 3 Package is designed for builds where "enough" is never enough.

While Stages 1 and 2 offer incredible performance, Stage 3 provides a 100mm thick core and 3-inch cold-side plumbing that ensures your Barra engine never struggles for breath or suffers from heat soak, regardless of the boost pressure.

If you are building a high-mount beast or a record-breaking street car, this is the only package that will truly keep up.
