COBB 3-Port Boost Control Solenoid - Subaru WRX (VA)
The COBB 3-port boost control solenoid replaces the factory solenoid on the 2015-2021 Subaru WRX (VA), giving the factory ECU more precise and flexible boost control. COBB designed it for owners whose turbo upgrades, such as a larger turbo or an external wastegate, call for more precise control than the factory solenoid allows.
Note: Suits the FA20 WRX (VA), not the WRX STI. A tune is required. COBB warns that running a map made for the factory solenoid with a 3-port solenoid fitted causes severe over- or under-boost, so the tune and hose routing must match. Installation by a professional is recommended.
Features
- Accurate, consistent boost control through the factory ECU
- Plug-and-play 18-gauge wiring harness
- Nickel-plated 6mm (1/4") barbed fittings
- Rated to 120 psi (8.3 bar)
- Billet aluminium solenoid mount
Pairs Well With
- COBB Silicone Turbo Inlet - Subaru Impreza WRX STI (GR/GV) / WRX STI (VA)
- COBB Cast Turbo Inlet - Subaru WRX (VA) / Forester XT (SJ)
- COBB LF Bypass Valve - Subaru Impreza WRX/STI (GD/GG) / Impreza WRX STI (GR/GV) / WRX STI (VA)
