Torque Solution High Volume Intake Manifold For Use w/ DBW Throttle Bodies 06-14 WRX / 04-21 STI

Torque Solution High-Volume Intake Manifold for EJ20/EJ25 DBW engines is engineered for high-performance applications while maintaining OEM-style fitment. Cast from high-quality aluminum and CNC-finished at the flanges, this intake manifold ensures a precise fit and reliable performance.

The design increases airflow and air volume to the engine, making it ideal for high-horsepower builds or simply upgrading for a clean, standout look. It retains the stock throttle body position for easier installation compared to other aftermarket manifolds, with no modifications required to FMIC piping. Compatible with both OEM and aftermarket TGVs(see notes below), the manifold can also be converted to a forward-facing configuration by flipping the billet aluminum vacuum block (minor customization required).

Testing on both stock and rotated turbo setups has demonstrated significant gains in mid-range and peak power. The manifold comes in a natural raw aluminum finish, ready to install or coat to your preference. Most necessary hardware for installation is included.

Features:

• CNC-machined cast aluminum construction
• Increased volume over OEM intake manifold
• Large, tapered, and radiused runners for optimal airflow
• Retains stock throttle body position for easy installation
• Compatible with OEM and aftermarket TGV housings
• Standard or reverse rotation capable
• Reversible billet aluminum vacuum block
• Works with FMIC piping that fits OEM manifold
  

Notes:

• 2006-2014 WRX Engines may require additional parts needed for STI Intake Manifold Swap
• 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. 
  
• 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.
