Intake Manifold With Port Injection Fuel Rails - FA2L WRX

The DITTO RACE (Direct Injection Tubular Original) is the ultimate intake solution for high-horsepower 2015-2021 Subaru WRX builds. While the standard DITTO manifold revolutionizes airflow, the RACE version is specifically engineered for tuners and racers who have pushed the factory direct injection system to its absolute limit.

Integrated Port Injection

The standout feature of the DITTO RACE is the inclusion of four additional port injector mounts and high-flow fuel rails. This hybrid fueling capability allows you to transcend the limitations of the factory DI system.

• 1000+ HP Capacity: Designed to house any EV-14 specification fuel injector, providing the fuel volume necessary for elite-level power figures.

• Tuning Flexibility: Gives tuners the ability to supplement fueling via an aftermarket ECU or injector driver, ensuring safe and consistent AFRs under extreme boost.

• Future-Proof: Even if you aren't at 1000hp yet, the RACE manifold provides the infrastructure to grow without needing to replace your intake manifold twice.

Performance & Flow Engineering

At its core, the DITTO RACE utilizes a precision-engineered billet plenum mated to large-bore cast runners.

• Optimised Cylinder Filling: Computer-designed internal porting and increased plenum volume ensure maximum air delivery to every cylinder.

• Measurable Gains: Developed over 12 months of in-house R&D, this manifold provides immediate power and torque improvements that scale upward as you increase boost.

• ‘NO CEL’ Compatibility: Despite its racing pedigree, the manifold is designed to operate on a standard vehicle without triggering a Check Engine Light.

Application & Fitment Notes

The DITTO RACE is a direct-fit solution for most intercooler configurations, though some setups require specific hardware:

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

• Front Mount Intercoolers: Direct fit for all kits currently using the stock inlet manifold.

• Top Mount Intercoolers: The Khanacooler and other aftermarket TMICs may require minor modifications to mounting brackets and under-hood ducting.

Note: While Process West provides the manifold and fuel rail hardware, secondary injectors and the electronic management hardware (ECU/Driver) must be sourced separately.
