Description:APS WRX STi Blow off Valve Top Mount Intercooler (BOV)
[APS 995-047-000]
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 1.375" (34 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 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.
Fine adjustment to blow off valve operation can be performed through the actuation adjustment screw for optimum configuration

The best bov ive ever used. The performance exceeded my expectations. Other bov's that i have tried made my idle irratic and caused my check engine light to come on. With this bov my idle is smooth and the shifting has improved no more lag between shifts. If your lookin for performance this one is for you. If your lookin for the loudest sound you will not want this bov.

I think this is the top of the line bov, if your looking for alot of sound this isn't for you. This bov is designed for the perfect sound which sounds so professonal.

Just Say No! To fully atmospheric Blow Off Valves. Cannot argue with APS design and quality. I will not recommend that you use this valve, I will recommend that you do not use any other valve!

This is the ONLY B.O.V. that should be installed on you WRX/STI. Don't be one of those nerds that only cares about sound! Get the sound you will ALWAYS be happy with along with the performance you and your ECU demand! Don't be a fool. Go for it.
