Kompact Dual Port - Mazda

Dual outlet-type BOV. The Kompact Dual Port vents both to the atmosphere and back into the air intake. Ports with sequential timing allow quieter operation during normal driving, while still offering the performance and sound of a vent-to-atmosphere BOV when the going gets harder. 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.
