I got 1 step coler plugs gapped at .028

it made a difference, cant really explain, but it did help. it was worth the $8

 

before I switched to colder plugs my spark would blow out

 

how do you know it was blowing out? is the reason you gap them closer, i understand it makes the spark length shorter and i understand if you have an aftermarket ignition you can gap it more because the spark is stronger. but does the extra air blow out the sspark. i am interested to know what goes on, and how you know if the spark blows out.

 

^yes, you will misfire if the spark gets blown out, so no spark=no ignition=no power=---- haha

 

go stock gapped down to 28 or 1 step and do the same, either worked fine for me.
