Walker Wire Oxygen Sensors are designed to determine the oxygen content of exhaust gas. A properly functioning oxygen sensor will improve fuel economy, increase engine response, and produce lower emission. Walker Products assembles all of their sensors to meet or exceed OE specifications. Walker Products supplies OEM based direct fit sensors to help speed up installation and make replacing a sensor a very simple project. The Walker Products O2 sensors are form, fit, and function to the original unit in your vehicle. This oxygen sensor also plays a key role in keeping your catalytic converter healthy.
