This wrench has been designed for use with most all oxygen sensors no matter what size electrical connectors they have.
The 12 point side enables the technician twice the number of "clock angle" attachment positions versus all oxygen sensor wrenches available on the market. This gives the technician the maximum accessibility to remove oxygen sensors in difficult areas.
The new handle design allows the technician greater space and positive leverage in confined areas. With 12 point positioning and a pivoting handle the #67750 will make a tough job easy.
The back side of the wrench has a 6 point for those stubborn sensors.
