When mounting the oxygen (O2) sensor in our turbo downpipe, you need a little extra wire. Some headers also require relocation of the O2 sensor as well.
This 6″ extension harness plugs right in with no need for wiring modifications. It also comes with a bracket clip for proper mounting.
Compatible with the single wire 1990-93 sensors only, not the four or five wire type found on later Miatas.
