    great, quality replacement for old O2 sensors

    well, the mustang used to run a little on the rich side, swapped out my 02's for these and once again she is running good. you wont see a performance gain unless your existing sensors are fouledor reading incorrect, but it is always good to have a quality replacement for when that happens
