Kompact Dual Port BOV for Subaru 98-00 Forester and MY99 WRX

The Kompact Dual Port is a dual outlet-type blow-off valve (BOV) designed specifically for the Subaru 98-00 Forester and MY99 WRX. This valve vents both to the atmosphere and back into the air intake, featuring ports with sequential timing for quieter operation during normal driving. When performance demands increase, it delivers the characteristic sound of a vent-to-atmosphere BOV.

Constructed from highly durable machined billet, the Kompact valve addresses the common issue of compressor surge that standard valves often fail to eliminate. As vehicles age, mass-produced valves can fatigue and leak, leading to severe boost leaks that hinder turbo performance.

With an anodised billet aluminium body and a lightweight alloy piston, the Kompact offers exceptional durability, superior response, and excellent boost holding capability for its size. This BOV is ideal for owners of stock to lightly modified vehicles seeking the classic vent-to-atmosphere sound in an OEM-replacement, space-efficient design.
