BOV Dump Valve Atmospheric for Subaru Forester XT Turbo Direct Bolt On Intercooler Fit No Extra Kit Required
Upgrade your Subaru Forester XT Turbo with this atmospheric BOV Dump Valve and enjoy the satisfying whoosh of vented boost while sharpening throttle response. Designed for Subarus that use a factory recirculating valve, this BOV bolts directly onto the intercooler with no extra fitting kit required, delivering a clean, bolt-on upgrade for enthusiasts who want that unmistakable open-vent sound.
Main Description
Built with a full twin-piston design and CNC-machined aluminium body, this atmospheric blow-off valve is engineered for reliability under boost. The internal piston is coated to reduce friction, ensuring smooth operation across the boost range. It vents to atmosphere, producing the characteristic “tschhhh” sound that turbo enthusiasts crave, while the anodised finish protects against corrosion in challenging driving conditions. The unit is direct OEM bolt-on to the intercooler and is fully serviceable, so you can maintain peak performance over time.
Included is a blanking port for the redundant recirculation pipe, allowing a clean removal of the factory closed-loop valve. The system is compatible up to 60 psi, making it suitable for most typical aftermarket boost setups. Note that this part is designed for older Subaru models with a factory recirculation valve and has been specifically tested for Subaru Impreza 1999–2000 GC/GC8 Turbo, Turbo 2000, WRX, STI, Type R, P1 variants. It will not fit other Subaru models outside the listed fitment. Professional installation is recommended, and installation of an atmospheric BOV involves changes to the vehicle’s stock boost management.
