Vibrant Heat Sink Oxygen Sensor Weld Bung T304 SS (M18 x 1.5 Thread)

If you're fabricating a custom exhaust system and need to add a port for an oxygen sensor, this weld bung from Vibrant is a smart choice. It's specifically designed to accept a Bosch LSU 4.9 oxygen sensor, which is common in many performance applications. Adding this bung allows you to properly position your sensor in your new exhaust piping.

What sets this bung apart is its heat sink design. The finned surface is optimized to help dissipate heat away from the oxygen sensor. This can make a notable difference in keeping the sensor cooler, potentially preventing premature failure that can happen when sensors are exposed to extreme exhaust temperatures. The material is T304 stainless steel, which is a solid choice for exhaust components because it resists corrosion. Plus, the coped design makes it easier to get a good weld fit onto your exhaust pipe.

This bung uses an M18 x 1.5 thread size, which is standard for many wideband oxygen sensors, including the Bosch LSU 4.9. Make sure you have the correct tools and welding supplies on hand when you plan to install this part.
