Torque Solution High Volume Intake Manifold - Subaru WRX (GD / GG / GE / GH) / WRX STI (GD / GR / GV / VA)

The Torque Solution High Volume Intake Manifold suits drive-by-wire EJ20 and EJ25 engines in the Subaru WRX and WRX STI. It is cast aluminium with CNC-machined flanges, and its large tapered, radiused runners add flow and volume over the factory manifold for high-power builds.

The throttle body stays in the factory position, so FMIC piping that fits the factory manifold in standard rotation bolts straight up. It works with factory and aftermarket TGV housings, and flipping the billet vacuum block allows a forward-facing layout (with some customising). Torque Solution testing showed gains in mid-range and peak power on both stock-location and rotated turbo setups. It is supplied in raw cast aluminium, ready to fit or powder coat.

Fits the Subaru WRX 2006–2014 (GD/GG/GE/GH) and WRX STI 2004–2021 (GD/GR/GV/VA) with drive-by-wire throttle bodies.

Note: Drive-by-wire throttle bodies only. Stock-location turbo setups need a minimum 19mm IM/TGV spacer, such as Torque Solution TS-SU-478-TGV (lower) or TS-SU-811 (upper), for inlet clearance. WRX models may need the extra parts normally used for an STI manifold swap. Update 6/1/25: do not use the billet brake booster check valve supplied in the kit; reuse the factory brake booster hose (it has a built-in check valve) and extend it with the supplied 3/8in hose barb joiner and 3/8in ID hose. Top-mount intercooler fitment is not confirmed by Torque Solution. Installation by a professional is recommended.
