Review: Easy to do. - I did spray the original 02 sensor for a week w/ WD40 and when it arrived my son used a 22mm box wrench to remove and install the new sensor. Remember to check the electrical outlet and make sure it matches before you replace the sensor. Took longer to walk down the driveway than it took to replace the sensor, 25 minutes tops. ,
Review: Great for the price - Works and fit well great option for the price
