TurboSmart BOV Kompact Dual Port Mazda

Dual outlet-type BOV. 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 still offering the performance and sound of a vent-to-atmosphere BOV when the going gets more challenging.

The standard blow-off valves on these cars are made of plastic, unlike the highly durable machined billet construction of the Kompact. 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 car ages, the plastic becomes brittle and can crack, 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 stock owners to lightly-modified cars looking for the classic vent-to-atmosphere BOV sound in an OEM-replacement, space-efficient package.
