Review on 🔧 Universal Automotive O2 Oxygen Sensor Socket Tool Set – 3 Piece Kit with 1 Vacuum Switch Socket & 2 Puller Sockets Wrench – Professional Grade 7/8”/22mm Removal Tool for Cars & Automotive - Ram-Pro by Richard Gross

Black painted crows (3/8" and 1/2" drive are not designed for surface drive; they have an angled contact and can use the hex on Shear off O2 sensors.The silver base is the only surface drive.You won't be changing your oxygen sensors on a regular basis so probably worth this set.The snap-on O2 sockets are around $70 each.Made in China as expected.
