If your engine is tossing you a check engine light for your oxygen sensor, replace it with this unit. The O2 sensor measures the amount of unburned fuel in the exhaust pipe to adjust fuel mapping for less emissions and better fuel economy.
When malfunctioning, your MPG and performance can suffer. Replaced fairly easily, you can restore your performance and mileage quickly. Put some anti seize on the threads to prevent it from becoming a permanent part of the exhaust.
We recommend using an oxygen sensor tool to remove and install this part. Check out the oxygen sensor tools offered on our site to assist you in your sensor replacement. Don't struggle with it by using the wrong tools. Make life easier and pickup ES#240942 or ES#5026!
