Overview

The ADD W1 BOV Sound Plate Adapter is designed for Kia and Hyundai 2.0T turbocharged vehicles. It allows unused charge air to vent to the atmosphere when the throttle is lifted, creating a more noticeable blow-off valve sound. This adapter installs between the OEM bypass solenoid and the turbocharger. It is constructed from billet aluminum with a black anodized coating.

It is precision CNC-machined from lightweight billet aluminum and features a durable black anodized finish for corrosion resistance and a sleek appearance.
