Thread: Autolite AR103 better than copper core 103s?

looked around on here cant find it sooooooo......Does anyone on here run or have tryed the Autolite AR103? My GP has full built motor top&bottom, full stack intercooler, ported heads, xpz cam, 60lb injectors, hd trans, high ratio rockers, 3.0 pulley, devilsown meth, headers, etc etc.......is there any gains in them from the regular copper core 103s?

keep in mind youd be changing em more often

thanks for telling me that i was most worried about do i have to keep swaping them out

If you have spark blowout problems then the ar is an easy fix. I back cut my own AL plugs though.
