Torque Solution High Volume Intake Manifold for 06-14 WRX / 04+ STi (TS-SU-675)

The Torque Solution High Volume Intake Manifold for Subaru WRX (06-14) and STI (04-21) with EJ20/EJ25 DBW engines is designed for optimal airflow and increased power in high-horsepower builds. Made from cast aluminum with CNC-machined flanges for precision fitment, this manifold retains the stock throttle body position for a straightforward installation, eliminating the need for custom piping. It is compatible with all OEM and aftermarket TGVs and can be reversed for forward-facing configurations with minor customization. Tested on stock and rotated turbo setups, it delivers impressive gains in both mid-range and peak power. Available in a raw aluminum finish, it can be bolted on as-is or powder-coated to match any aesthetic preference.

PDF Install Guide

• Works with FMIC piping kits that fit the OEM IM in standard rotation.
• 2006-2014 WRX: Additional parts normally needed for STI IM swap may be required to install.
• 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.

More Info:
Large High Volume Plenum
We ensured that the internal plenum design offered the best flow from the throttle body to the runners. By centering the throttle body opening and minimizing internal obstacles, we were able to maintain optimal flow with reduced turbulence.

Stock Throttle Body Position
Retaining the stock throttle body position makes installation a much easier task, as there is no need to have your FMIC piping modified to fit!

Large Runners
The large-volume tapered runners feature internal radiused edges to ensure a smooth flow. It also has CNC-machined flanges for a perfect fit.

Bottom Mount Vacuum Block
Integrated bottom-mount vacuum block. Fully reversible to allow for standard or forward-facing configurations! *We also include everything necessary to complete the installation!
