Process West Intake Manifold w/ Port Injection Fuel Rails – Subaru WRX FA20 2015-2021 Process West

Designed for the MY15+ FA20DIT WRX the Process West ‘DITTO’ (Direct Injection Tubular Original) compromises a mix of billet plenum and cast large bore runners to achieve the highest intake flow rates possible.  Over 12 months from initial design to testing on our own in-house WRX has allowed us to ensure not only guaranteed performance gains (see attached dyno sheet of a totally standard WRX with and without DITTO) but also perfect fitment. Note DITTO is a direct fit for Process West top and front mount intercooler equipped vehicles.* (see application notes below).

Power gains come from computer designed and tested internal plenum porting and an overall larger volume and greater runner capacity for optimal cylinder filling. Not only does DITTO offer these advantages but it is also part of our new ‘NO CEL’ product range that allows fitment to a totally standard vehicle with no Check Engine Light or Tuning required. Obviously even further improved results can be achieved in tuned versions of the FA20, with our experience showing the greater the power output, the greater the gains!

The Port Injection DITTO RACE version provides unmatched tuning flexibility in the form of an additional 4 port injector mounts. Designed to take any EV-14 specification fuel injector this delivers tuners the flexibility to add substantial extra amounts of fuel from an aftermarket ecu/injector driver to give a true 1000+hp worth of capacity. Whilst Process West don’t offer the computer hardware, we do deliver the functionality that highly tuned engines need.
