What is the difference between Dual Port, Vent to Atmosphere, and Plumb Back?

Dual Port vents some air to the atmosphere for sound and some back to the intake for smoother idle. Vent to Atmosphere (VTA) vents all boost to the atmosphere, creating a loud "pssh" sound. Plumb Back recirculates all boost back into the intake system, which is quieter and often preferred for stock-like drivability.

Does this blow-off valve come with everything needed for installation?

Yes, this Turbosmart Kompact Dual Port Blow Off Valve is designed as a direct-fit replacement and includes a blanking plug to allow for different venting configurations.

Can this blow-off valve be used on other Hyundai models?

While this specific part number is listed for the 2019-2021 Hyundai Veloster N, Turbosmart also offers Kompact BOVs for the Hyundai i30N and Kona N models.

Product Details

This Turbosmart Kompact Dual Port Blow Off Valve is a direct-fit upgrade for your 2019-2021 Hyundai Veloster N. It replaces the factory plastic unit with a well-built billet aluminum construction designed for improved performance. The Dual Port design allows you to vent some air to the atmosphere for that classic blow-off valve sound, while also recirculating some air back into the intake. This setup helps maintain proper idle and drivability during normal driving, but still gives you the full effect of venting boost pressure when you're pushing the car hard.

The Kompact BOV is made from aerospace-grade aluminum and features high-temperature seals. These seals are crucial for minimizing boost leaks and ensuring a complete seal when the valve closes, which helps you hold onto that boost pressure more effectively. Turbosmart manufactures and assembles these units in-house, ensuring solid construction. It also comes with a blanking plug, giving you the flexibility to switch between a full vent-to-atmosphere setup or a full recirculating (plumb-back) mode if you prefer.
