Titanium NPT sensor bungs are fittings made of titanium. They are used to mount oxygen sensors in the automotive exhaust system. It is an essential component in modern automotive systems. They are responsible for measuring the amount of oxygen in the exhaust gases. The engine management system uses this information to adjust the air-fuel ratio in real time. It improves engine performance and reduces emissions.
