Steel Bung/Plug Kit

The Innovate Motorsports Steel Bung/Plug Kit (part number 37350) is designed for engine builders, tuners, and fabricators who need to integrate aftermarket exhaust systems and data acquisition equipment. This kit includes a straight steel bung and a protective plug, providing a complete solution for safely mounting 18mm x 1.50 female-threaded sensors into custom or modified exhaust headers.

The bung features an 18mm diameter with a 1.50 female thread pitch, which is a common specification for certain oxygen sensors. Its straight configuration allows for direct sensor mounting perpendicular to the exhaust pipe wall, which helps minimize turbulence and ensures accurate readings. The natural steel construction allows for welding, typically requiring standard MIG or TIG equipment for permanent installation.

This kit is particularly beneficial for tuners building custom headers, engine builders integrating closed-loop fuel control systems, and fabricators working on projects where factory sensor bungs are unavailable or incompatible. Users transitioning from carbureted to fuel-injected engines or upgrading exhaust systems on late-model vehicles will find this kit essential for their modifications.
