O2 Sensor Bung Universal Steel Weld

The ICT Billet O2 Sensor Bung Universal Steel Weld is a precision-engineered oxygen sensor port designed for custom exhaust system fabrication and engine tuning applications. This weld-on bung accommodates an 18 mm x 1.50 female thread and provides a reliable mounting solution for aftermarket oxygen sensors used in EFI tuning, carbureted engine modifications, and performance exhaust builds where factory sensor bungs are not present or need relocation.

Constructed from steel in natural finish, this universal oxygen sensor bung is built to withstand the thermal environment of exhaust systems while maintaining thread integrity under repeated sensor installation and removal cycles. The straight configuration and metric 18 mm x 1.50 female thread specification ensure compatibility with standard oxygen sensors used in standalone engine management systems and aftermarket fuel injection controllers. The kit includes plugs, allowing users to seal the bung during welding or for temporary closure when a sensor is not installed. The compact 3.75-inch length facilitates integration into tight exhaust manifold and header designs.

This bung is essential for engine builders, fabricators, and performance tuners who require a robust, weld-on oxygen sensor mounting point for custom exhaust systems. Common applications include LS engine swaps, turbo and supercharger installations, carbureted-to-EFI conversions, and custom chassis builds where standard sensor bungs are unavailable or impractical. The universal design and straightforward weld-on installation make it a standard component in engine shop inventory and DIY fabrication projects requiring sensor data acquisition capabilities.
