Mitsubishi EVO 8 & 9 4G63 Rear OEM Bosch Denso Oxygen Sensor

Bosch/Denso invented the automotive oxygen sensor and is the number one choice of vehicle manufacturers around the world. Properly functioning oxygen sensors are important when it comes to your vehicles fuel efficiency and reducing harmful exhaust emissions. That's why checking for, and possibly replacing, a worn-out oxygen sensor is an important part of every routine vehicle tune-up. Replacing a worn-out oxygen sensor saves money in fuel costs, improves engine performance, reduces air pollution and prevents premature failure of the catalytic converter. And when you use Bosch/Denso Oxygen Sensors along with Bosch/Denso Spark Plugs as part of a Bosch/Denso Premium Tune-up, youll be helping the environment and your vehicles fuel economy over the life of the oxygen sensor.
