Titanium Oxygen Sensor B ung M18 x 1.5

The Titanium Oxygen Sensor B ung M18 x 1.5 from VIBRANT PERFORMANCE is a precision weld-on bung designed for custom exhaust system builders and automotive tuners who need reliable oxygen sensor integration. This component serves as a mounting point for oxygen sensors in fabricated exhaust manifolds, downpipes, and custom exhaust headers where factory sensor locations don't apply. Whether you're building a high-performance engine management system or retrofitting a modified vehicle, this titanium bung provides a durable, threaded interface that withstands extreme exhaust temperatures.

Constructed from aerospace-grade titanium, the oxygen sensor bung features an M18 x 1.5 female thread that accepts standard oxygen sensor fittings with precision fitment and zero leak potential. Titanium's superior heat resistance and low thermal conductivity make it ideal for direct exhaust contact, preventing sensor reading errors caused by thermal shock or bung degradation. The weld-on design allows fabricators to position the sensor bung anywhere along the exhaust path, enabling optimal lambda measurement for tuning and emissions monitoring. The compact 3.15 x 3.7-inch profile minimizes package intrusion while the natural titanium finish resists corrosion from exhaust gases and moisture exposure over extended service intervals.

This bung is essential for engine builders, custom fabricators, and dyno facilities performing exhaust system modifications or engine swaps where OEM sensor bungs are unavailable or incompatible. It pairs seamlessly with any oxygen sensor featuring an M18 x 1.5 thread pitch, making it a universal solution for custom exhaust projects across multiple platforms. Installation requires TIG welding into the exhaust pipe or manifold; proper shielding gas and stainless or mild steel backing plates ensure a leak-free permanent joint. The lightweight 0.04 lbs design adds negligible weight while the titanium material ensures longevity in the harshest underhood environments.
