i might spray a 200 shot on my 460 and was wondering what the 124 and AR33 racing plug have in common and if the heat ranges are close !

124 is hotter and resistor style. AR33 would be better for your applicaion when on the spray.

so is the stock 45 plug hotter than the 124, because i know a few recommend the 124's over 45's. Thanks !

124s are a better fit than 45s.

The 124s are simlar in heat range to BF-32's

AR-33 are simlar to BF-22's

AR-34 are simlar to BF - 12's

ARalso has one colder than the 12's but not shure of the #
