Dual outlet-type blow off valve. Dual port vents both to the atmosphere and back into the air intake. Ports with sequential timing allow quieter operation during normal driving, while getting all the benefits of a vent-to-atmosphere blow off valve under race conditions. Easily converted to a full atmospheric or full bypass unit by using supplied port blanking plug. Fits most cars using the factory Bosch or Denso bypass valves, also Subaru Legacy/Liberty 09-10.

Excellent BOV
This is an excellent, high quality blow off valve. The machining is flawless and it's perfectly functional. I am extremely happy with this purchase.

High Quality BOV
Very nice sound that is not ricey. Also looks pretty stealthy, but is obviously of high build quality. I enjoy the adjustability.
