Process West DITTO Intake Manifold Subaru WRX (VA) FA20DIT

Process West DITTO Intake Manifold - Subaru WRX (VA) - FA20DIT

Process West has spent over a decade building high performance induction and cooling components for the Subaru platform, and the DITTO manifold is their most ambitious intake yet for the FA20DIT engine. Combining a billet plenum with large bore cast runners, it's engineered to lift cylinder filling and flow beyond what the factory manifold can offer. This is a direct upgrade for the Subaru WRX (VA) fitted with the FA20DIT engine, SKU PWIM007.

This listing covers the standard DITTO manifold for the Subaru WRX (VA). It's part of Process West's No CEL range, meaning it installs on a stock vehicle without triggering a check engine light or needing a custom tune, while still supporting bigger gains as boost and fuelling increase.

Note: fitment with aftermarket front mount intercoolers may need brackets or ducting modifications outside of the Process West Verticooler, which requires the separate PWIM007VFT fitting kit.

Key Features

• Billet aluminium plenum with cast high flow runners
• Increased plenum volume for improved cylinder filling
• Computer tested internal porting
• No tune required on stock vehicles
• Direct fit for Process West and most factory inlet based TMIC kits

Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please confirm your vehicle's engine code and intercooler setup before ordering.
