i have not tried them on the 92, but i did on the 71. they made no diff on the dyno. we tried 3 diff sets of plugs, stock ac, bosh platnum, and splitfires. on the dyno there was no diff. i don't know about fuel milage or long term effect as i stayed with the ac plugs. for the cost i couldn't justify using then with no proven gain. its just my opi but a well tuned motor with a proper ign system and right heat range plug worked best. i tryed to find a reason to use them and couldn't. robert
