Buying this part to pass state inspection saved me from the 100% markup charged by my previous repair place. They billed more than $100 each for my previous two O2 sensors, although it's possible they paid a premium to get genuine Mitsubishi parts. This time, I bought it from Parts Geek and got a different mechanic to install at a very reasonable price. I passed inspection a day and a half later. Few people could install this part themselves. This is probably the toughest of the 4 sensors to replace. Make sure you have somebody good doing the work.
