Works great, used it while installing a race header, I welded in a second O2 bung after the header since it only gives you a spot for the upper O2, and clipped this in between the rear O2 harness and the rear O2 sensor and have not had a check engine light yet. Car gets a false o2 reading and runs correctly.
Did not work had to buy a non defouler
