The Process West DITTO (Direct Injection Tubular Original) represents the pinnacle of intake engineering for the FA20DIT platform. By combining a precision billet plenum with high-flow, large-bore cast runners, the DITTO manifold delivers the highest intake flow rates currently available for the VA WRX.

Engineering & Performance

Developed over 12 months of rigorous in-house R&D, the DITTO manifold is designed to optimize cylinder filling through increased plenum volume and computer-tested internal porting.

  • No Tune Required: As part of our ‘NO CEL’ range, this manifold can be installed on a completely stock vehicle without triggering a Check Engine Light or requiring a custom map.

  • Proven Gains: Performance increases are immediate and measurable even on standard vehicles, with gains scaling significantly as power levels increase on tuned applications.

  • Build Quality: A premium hybrid construction utilizing billet and cast aluminum for maximum strength under high boost.

Versatility & Fitment

The DITTO is designed as a direct-fit solution for vehicles already equipped with Process West cooling systems, though it is compatible with a wide range of setups.

  • Front Mount Intercoolers: Direct fit for all kits that utilize the stock inlet manifold.

  • Process West Verticooler: Requires fitting kit (Part Number: PWIM007VFT).

  • Other TMICs: The Khanacooler and other aftermarket top-mounts may require minor modifications to mounting brackets and under-hood ducting.

DITTO RACE: The 1000+ HP Solution

For high-horsepower builds, we offer the DITTO RACE version. This variant includes four additional injector ports designed to house any EV-14 specification fuel injector.

This provides tuners the flexibility to supplement the factory direct injection with port injection, delivering the fuel volume necessary to support 1000+ hp builds. While Process West provides the manifold functionality and hardware, an aftermarket ECU or injector driver is required to manage the secondary fuel system.

Note: For maximum results, we recommend pairing the DITTO manifold with high-flow charge pipes and optimised intercooler setups.

In Pursuit of Something More. 

There’s more power in that engine, but your stock intake is suffocating it. Our intake lets it breathe.

Ground-Up Performance Engineering.

Our designs all follow a similar path. We remove the stock intake manifold 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. 

Tested & Independently Verified.

We take our product testing one step further. Every new Intake Manifold is sent to specialist tuners who confirm installation ease, power gains, and reliability.

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 building Intake Manifolds and innovating airflow dynamics for over 20 years. Every intake we develop is designed to set new performance benchmarks in turbocharged builds.
