This O2 sensor is way cheaper and I'll tell you why. The pin part that goes into the electrical connector is not suitable. I thought it was me, but when I took the old O2 sensor and put it in, it went in easily. I had to go back to the parts store as my truck was stuck on some ramps and buy a $90 Bosch system with military rebates/taxes. I saw the same style on their monitor at an auto parts store and told them I would pay extra for one that would fit. Cheap fake, can't tell if the sensor was good or just a bad fit. On the website showing the installation they said the touch part should be protected by a plastic cover but not here.
