Innovate Motorsports 37640 Extended O2 Sensor Bung and Plug Kit Mild Steel 1 Inch

The Innovate Motorsports 37640 Extended Bung and Plug Kit is designed for wideband oxygen sensor installations in small diameter exhaust tubes and high-performance applications. This kit features a 1-inch extended depth mild steel weld-on bung with M18 x 1.5 female threads and includes a matching plug for sealing the port when the sensor is not installed.

Key Features:

• Extended 1-inch length provides additional clearance from exhaust flow
• M18 x 1.5 female threads accept Bosch LSU 4.2 and 4.9 wideband sensors, NTK wideband sensors, and most OEM narrowband sensors
• Mild steel construction for durability and weldability
• Ideal for smaller diameter tubes where standard bungs would place the sensor too close to exhaust flow
• Helps protect sensors from excessive heat when mounted near exhaust ports or turbochargers
• Reduces sensor heat soak and exposure to contaminants that can cause fouling
• Includes plug for secure, airtight seal when capping unused ports

This extended bung is a direct replacement for the standard parts included with Innovate Motorsports wideband kits and is compatible with all Innovate wideband controllers. The longer design positions the sensor head out of the direct exhaust path, potentially improving flow while protecting sensitive electronics from damaging high temperatures.
