When selecting a replacement, choose from narrow-band and wide-band sensors, with the former being the most common for older models and the latter for newer, performance-focused vehicles. Remember to opt for high-quality materials to withstand the harsh exhaust environment, and consider pre-installation tips such as applying anti-seize to the threads without contaminating the sensor's business end.
