Turbosmart BOV Kompact Dual Port - Subaru 02-07 WRX, 04-21 STI, 06-07 Forester XT - TS-0203-1015

Dual outlet-type BOV. The Kompact Dual Port vents to 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. The standard valves are often not up to eliminating damaging compressor surge, and as the car ages, the plastic becomes brittle and can crack, causing severe boost leaks. This prevents the turbo from reaching its full potential, robbing you of performance.  With its anodized billet aluminum 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.   Fitment: Subaru Forester 06-07 Subaru Forester XT 2.5 EJ255 Subaru WRX 02-05 Subaru Impreza WRX 2.0 Turbo EJ205 06-07 Subaru Impreza WRX 2.5 Turbo EJ255 Subaru STI 04-07 Subaru Impreza WRX STI 2.5 Turbo EJ257 08-14 Subaru Impreza WRX STI 2.5 Turbo EJ257 15-21 Subaru WRX STI 2.5 Turbo EJ257
