The Kooks universal oxygen sensor bung plug is a stainless steel O2 sensor plug intended to seal unused oxygen sensor ports in headers and exhaust systems. It's a simple solution for closing off ports during fabrication or when running standalone setups. Made from stainless steel for corrosion resistance, these universal bungs provide a durable, welded-in port closure that preserves exhaust integrity and keeps sensor threads protected when a sensor is not installed.
