APS Dual Vent BOV Kit for 2002-5 WRX and 2004-5 STi #16855

APS High Volume Twin Vent Blow Off Valve The Subaru Impreza WRX/STI has unique blow off valve requirements particularly when fitted with a large turbocharger. A blow off valve is a device that releases pressure from the turbocharger when the throttle is released. APS designed the APS high volume twin vent blow off valve specifically for the Subaru Impreza WRX/STI. It is an ideal enhancement for applications using the standard turbocharger up to large 600 hp units. With its huge capacity the APS blow off valve gives you the ultimate in turbocharger durability and improved turbo response particularly during gear changes. A mammoth 1.417" (36 mm) internal bore size delivers huge capacity and at full piston travel, all ports are fully exposed for maximum blow off volume. The APS twin vent BOV features 30 micron hard anodized, T6 billet aluminium body, low friction bronze piston, all stainless steel hardware including spring and Viton 'O' rings. The large primary vent is designed to plumb back to the standard entry point which ensures the best driveability during cruise conditions and cures the erratic idle and engine's rich condition (on gear changes) problems seen with after market external single venting blow off valves. And for large turbochargers running high boost pressure levels, the APS twin vent blow off valve continues to vent through to the second stage port.
