Torque Solution High Volume Intake Manifold Subaru 2006-2014 WRX / 2004-2021 STI

Torque Solution High Volume Intake Manifold for Subaru WRX 06-14, STI 04-21 EJ20 / EJ25 DBW engines is the perfect addition to your WRX / STI. Made from cast aluminum using a metal casting process and then finished off by CNC'ing the flanges for a perfect fit. Our intake manifold design allows you to increase the flow and air volume to your engine making it ideal for high HP applications or if you just want to stand out from the crowd with it's sleek clean design. Our IM retains the stock TB position which results in a much easier install over other IM's on the market. No need to modify or make custom FMIC piping to complete the install!! Also, works with all OEM / aftermarket TGV's!! The TS IM is also easily reversible to a forward-facing configuration by simply flipping the vacuum block (customization will be required for forward facing)!! We feel these features make our IM the most versatile available on the market!!! The intake manifold comes as a natural raw aluminum finish. Ready for you to bolt on and use or get powder coated to your liking.

- Retains Stock Throttle Body Position
- Works w/ OEM and NON-OEM TGV Housings

Notes:
- Stock location turbo configurations will need to run a minimum 19mm IM/TGV spacer, such as PN: TS-SU-478-TGV (lower) or TS-SU-811 (upper) for added inlet clearance (confirmed to fit with ALL known inlets while using the spacers).
- Boomba DBW throttle body is direct bolt on without any added adapters.
- TMIC install may be possible with some smaller TMIC's and custom brackets. We cannot confirm this, as we will not be testing these configurations.
- 6/1/25 Update: Please no longer use the billet brake booster check valve provided in the kit. Reuse your OEM brake booster hose, which has a built in check valve near the booster side of the hose. Use the newly supplied 3/8 to 3/8 hose barb joiner and the supplied 3/8 ID hose to extend the OEM hose. Cut the supplied 3/8ID hose to suit your needs and hose routing to the IM vacuum block fitting.
