Kompact Dual Port Blow Off Valve Suit MY99-00 WRX, STI and MY98-00 Forester GT

Dual outlet-type BOV explicitly designed for the Subaru 98-00 Forester and MY99 WRX. The Kompact Dual Port vents into the atmosphere and back into the air intake. Ports with sequential timing allow quieter operation during everyday driving while offering the performance and sound of a vent-to-atmosphere BOV when the going gets more demanding.


The Turbosmart Kompact valve is a highly durable machined billet construction. This prevents the turbo from reaching its full potential, robbing you of performance. This prevents the turbo from reaching its full potential, robbing you of performance. The standard valves are often not up to the task of eliminating damaging compressor surge, and as the cars age, the mass-produced items fatigue and leak, causing severe boost leaks.

With its anodised billet aluminium body and lightweight alloy piston, the Kompact offers extreme durability, superior response and excellent boost-holding capability for its size. 

The Kompact Dual Port is perfect for owners of stock to lightly-modified cars looking for the classic vent-to-atmosphere BOV sound in an OEM-replacement, space-efficient package.
