Once you find the Denso part number (Denso is OEM) you can check around for the best price. I got mine online at Walmart shipped to store (took 5 days to get it). I have the 2.5 engine and it only took me 20 mins to change.(dealer wanted 350.00 to do it) Make sure you spray lots of PB blaster or some penetrating oil on it and let it sit overnight. You might want to get a 02 sensor Socket to get the sensor off. Also make sure you put the anti seize paste on the threads on the new 02 sensor. Let us know how it goes !Frehley76;210te9521 said:Thanks, that helps a lot. I am going to order one and give it a shot.
