To install an HKS blow-off valve (BOV) on a Mitsubishi VR-4, start by locating the factory recirculation valve, which is usually found on the intake manifold. Remove the factory valve and any associated piping. Next, install the HKS BOV using the provided flange and clamps, ensuring it’s securely mounted.
