Sometimes oxygen sensors can be difficult to reach with just a wrench. They are too deep inside the engine, the wires get in the way, they are set at an angle a wrench can’t get near. This set solves those problems with three different oxygen sensor sockets perfect for every situation. The shallow 7/8” (22mm) socket is offset to make turning easier. The other two are deep, one straight, one offset, to reach sensors out of reach of other sockets. The deep socket can also be used to extract many common vacuum switches. All three have a slot to allow wiring or vacuum nipples to extend outside the socket wall. Strong and dependable enough to last a lifetime.
