Does anybody know what the best spark plugs are for a 87 5.0. I have some Bosch Platinum +4 and they seem to work fine, but a buddy of mine put some NGK in his and he said his performed better. Just curious. Thanks
ECU5.0 said:ngk or autolite 24's i think are what most people run on stock heads. aluminum heads require a different plug, i think the autolite 3924
ECU5.0 said:if you gap them more than stock it takes more current for the spark to jump the longer distance. obviously its not a big difference, but it does take more juice to do it. gapping them too small will shorten the spark and wont burn the fuel mixture as completely. i think thats the way it works anyway

r6bullet said:also the platinum +4 is a joke, the spark is always going to go to the best way to ground which = using only on prong, not 4
