""This high quality part was a direct replacement for the Subaru factory oxygen sensor. It came complete with proper anti-seize compound and proper length cable. Remove and replace, DONE. And no fault codes to mess with and improved gas mileage compared to the original with 130,000 miles."" posted by: Sundance Kid on September 3, 2014 view all 1 reviews
