        Comments about Denso Oxygen Sensor - Direct Fit:

        My mechanic took pity on me when he saw the $200+ price tag on the part alone if he ordered it thru his suppliers: told me to get the part myself. He kindly installed this OE manufacturer direct-fit sensor for $40 even tho quoted me $50--so it must be easy to install. Yay for me!
