Tired of burning out O2 sensors on your pre-turbo O2 installation such as BMW N54? Well, now you do not have to. Our Thermo-Isolating O2 bungs either screw into your existing O2 bung, or weld into manifold or header isolating your O2 sensors from the direct heat a pre-turbo sensor sees. They do this by reducing the exhaust gases flowing over the sensor, as well as lift the element away from the hot manifold with 8 heat sinks for weld-in, and 4 for screw in. All VTT Thermo-Isolating O2 bungs are machined from Billet 310SS for extreme heat resistance. Screw-In compatible with any existing O2 bung for $35 each (4 heat sinks), weld-in for fabricator’s are $45 each (8 heat sinks). Available now.

Note: Bungs must be clocked with the hole facing into exhaust flow from them to work properly.
