i got some new plugs and have wires on the way from underdog performance, and picked one of those coin shaped gap readers. how do i increase the gaps with it, or do i need another tool to do that? i'm rather new at the spark plug thing.

 

just use the gaper to bend it till you get to the gap you need simple as that if you gap it to far juts push it against something hard to bend it back down but be easy with it

 

bend the hook thingy over the electrode?

 

ha, figured it out, knew it was something ridiculously easy.

 

with the screaming demon ignition setting the gap to 0.060 would be no problem? ok to do 65? yay nay?

 

if they are iridiums dont use the "coin" to bend the electrode.. you will snap it.. any other plug yeah you can use the coin..

 

how do you gap/measure 4 prong spark plugs?

 

you dont
