Product Description

The Torque Solution TS-BOV-687 HKS Blow Off Valve Adapter is a precision-engineered flange that allows enthusiasts to install an HKS blow off valve on select 2.5T turbocharged Kia and Hyundai models without any welding or modifications. Built from CNC-machined billet aluminum with a black anodized finish, this adapter is designed for durability and a clean, high-quality appearance.

This adapter fits specifically on 2021-2026 Kia Stinger and K5 2.5T models and 2022-2026 Hyundai Sonata 2.5T vehicles, providing a direct replacement for the factory recirculation setup while opening the option to add an aftermarket HKS BOV. Installation is straightforward using the supplied hardware and OEM gasket, making it ideal for performance enthusiasts looking to enhance turbo response, reduce compressor surge, or add that classic turbo sound when paired with a compatible blow off valve. Note that the HKS BOV unit itself is not included with this adapter.
