The Process West Billet TGV Delete Kit eliminates the factory tumble generator valves, removing a significant restriction from the intake path and maximising airflow under all operating conditions.

Precision machined for performance.

The port profile is machined to suit ported cylinder heads, ensuring a smooth, unrestricted transition from plenum to head. The upper flange surface is O-ringed for a reliable, leak-free seal against both stock and aftermarket plenums.

Two length options.

Available in 79mm and 67mm lengths to suit a range of build configurations. The shorter 67mm version is required when fitting a Process West Billet Plenum to a GC8.

Injector and fuel rail compatibility.

Injector ports are machined to accept both 11mm and 13mm diameter injectors without adaptors. Simply use the supplied Viton O-rings to suit your injector size. Fuel rail mounting points match the factory specification, making the kit compatible with stock and aftermarket fuel rails alike.

A precise, well-engineered upgrade for any serious WRX build looking to remove intake restrictions and support higher power levels.

The Process West Charge Pipe Kit is engineered to be the premier flow solution for the VA WRX platform. By replacing the restrictive factory unit with a high-flow alternative, this kit optimises the air path between the turbocharger and the intercooler for improved throttle response and consistent power.

Key Features:

• High-Efficiency Flow: Features a significantly smoother internal bore compared to the factory pipe, reducing turbulence and boost restriction.

• Two-Piece Design: Unlike cumbersome single-piece alternatives, our two-piece construction ensures a frustration-free installation in tight engine bays.

• OEM+ Aesthetics: Finished in a durable black powdercoat, providing a professional, factory-integrated look that complements any engine bay.

• Complete Bolt-On Kit: Includes all necessary high-quality silicone couplers and heavy-duty clamps required for a secure, leak-free fitment.

Why Upgrade?

The factory plastic charge pipe is prone to expansion under boost and contains restrictive bends that hamper performance. The Process West kit provides the structural integrity needed for increased boost levels while streamlining airflow, making it an essential supporting modification for any tuned WRX.

The factory Focus ST airbox is designed with noise reduction in mind, not performance. Under high load conditions it generates a measurable pressure drop that costs power, even on a completely stock car. The Process West Cold Air Intake addresses this directly.

Best of both worlds.

Rather than a simple pod filter swap, the Process West system combines a low-restriction K&N pod filter with a purpose-built cold air divider and internal bell-mouth. This design captures the high-flow benefits of an open pod arrangement while retaining the cold air separation and consistency of a proper air box enclosure. The result is improved airflow, reduced intake temperatures, and more consistent power delivery under sustained load.

Complete kit.

High-volume pipework, custom moulded silicone hoses, and matching clamps are all included. The system works as a standalone upgrade or in conjunction with the Process West Intercooler system for a fully integrated intake solution.

A well-engineered intake upgrade that addresses a genuine weakness in the factory Focus ST setup.

The Process West Cold Air Intake is a direct replacement for the factory air box on the Next Gen Ranger Raptor, engineered to deliver a meaningful improvement in airflow, throttle response, and intake efficiency.

Improved intake sound.

Replacing the factory air box with the Process West Cold Air Intake delivers a noticeable improvement in intake sound. The high-flow K&N pod filter and less restrictive intake path produce a more pronounced induction note under acceleration, adding to the driving experience both on and off road.

High-flow filtration.

The system houses a large 6-inch K&N pod filter, delivering a substantial increase in airflow volume over the factory unit. The result is improved throttle response and more consistent power delivery across the rev range.

Compatible with factory and aftermarket crossover.

Works directly with the factory crossover pipe. For maximum system performance, the Process West 3.5 Inch Crossover Pipe is available separately in black or red (PWRRCP01B / PWRRCP01R).

Reduced heat soak.

The cold air intake design draws from a cooler air source than the factory air box, helping to reduce intake air temperatures and maintain consistent performance under sustained hard use.

Straightforward installation.

Designed for a clean, bolt-on fit with no cutting or permanent modification required. A straightforward install for any level of experience.

Addressing a well known issue with the Ford Ranger/Mazda BT50 this new product replaces the failure prone factory part with a high quality Process West piece that won't leave you stranded or in 'limp mode'. A great investment for your ute no matter if totally stock or highly modified

This crossover pipe kit will work alongside the Process West Stage 2 Intercooler Kit and Under Battery Cold Air Intake.

The upgrade crossover provides two primary benefits:

• Replaces the restrictive factory cross over pipe
• Allows fitting of the Process West Under Battery Cold Air Intake

The kit provides the opportunity to upgrade to the Stage 2 Intercooler Kit, Cold Air Intake, and Crossover.

Note: This unit is as large as possible, however maintains a 10mm clearance to the bonnet/hood. This could not have been achieved with bent aluminium tubes without resulting in a very awkward looking pipe.
