The Process West Silicone Throttle Coupler is a direct replacement for the factory joiner between the top mount intercooler and throttle body, built to a noticeably higher standard than the part it replaces.

Featuring a thicker wall construction and stronger silicone compound, it offers improved durability and greater resistance to heat and boost pressure over the long term. A straightforward upgrade that adds reliability to one of the most stressed connections in the intake system.

In Pursuit of Something More. 

There's more power waiting under the hood, Process West will help you get it. 

Ground-Up Performance Engineering.

Our designs all follow a similar path. We remove the stock component and 3D scan the engine bay to determine the precise constraints of the available space. Once we know what we’re working with, we generate functional renders and finalise form, function, and fitment.

Following our digital models, we generate 3D printed prototypes for further, real-world confirmation of size, fitment, and installation ease. When our prototype is perfect, it's on to manufacturing.

Proudly Built Down Under.

All our products are built in-house at our Australian facility. From billet aluminium CNC machining, welding, powder coating and packaging. 

Preferred By Record Holders.

You’ll find Process West in some of the quickest and fastest builds in the world, driven by those who only care about one thing. Results.

Pioneers Since 2003.

Process West is built on continuous innovation. We’ve been working on performance dynamics for over 20 years. Every component we develop is designed to set new performance benchmarks.
