HKS SQV IV Black Edition BOV (Boost Refrence Required) HKS Flange

PD Notes: Bov’s are generally a personal preference mod. It’s about what sound you like. Performance-wise, all of the bov’s generally perform the same on the OEM Flange. If you are planning on swapping out your turbo to a larger aftermarket unit, I would upgrade to charge pipes with a TiAL flange to allow the use of bov with a larger diameter valve like the Turbosmart Raceport. 

**This BOV does require a boost reference to work. We recommend the Turbosmart Boost Reference adapter to make the installation easier. Removing the factory electronic bov will cause a P0035 check engine light to show. This will not impact how the vehicle drives or performs in any way. If you would like a BOV upgrade without a check engine light, please see the Turbosmart EM BOV that we sell**

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure.
