Description
The GrimmSpeed 3-Port Electronic Boost Control Solenoid replaces the restrictive factory 2-port setup on the 2015-2021 Subaru WRX, giving your ECU faster, more precise control over wastegate duty cycle for sharper boost response and more consistent boost holding. Each solenoid is internally modified and prepared for the demands of a tuned turbo engine.
Features
- 3-port design for finer boost control than the factory 2-port solenoid
- Plug-and-play OEM connector, no wiring modifications required
- Custom machined black anodised aluminium adapter with Viton O-ring seal
- 1/4" zinc-plated barbed fittings with 1/8" NPT threads for barb or AN fitting options
- Zinc-plated steel bracket mounts in the factory location
- Fully assembled and ready to install
Fitment
- Subaru WRX VA, 2015-2021 (FA20)
- Suits the factory composite turbo inlet or the upgraded GrimmSpeed aluminium inlet
Notes
- Custom tuning is required after installation. Do not drive the car under boost until it has been properly tuned.
- Approximately a 30 minute install using the supplied instructions.
