Been using those coin gapers since I was a teen. Friend of mine gave me one of these and when I checked my gaps they were way off with feeler gauge. Can really adjust gap precisely to .043https://precisionraceworks.com/products/gap-tool-w-feeler-gauge

$40 tool to gap a $2 part? No thanks. I'll stick to my $1 gapping tool.

My understanding is the “coin” isn’t for adjusting the gap, but for measuring it. I’ve never used it to adjust the gap. Definitely not on modern Iridium plugs. I’ve always bought plugs with the gap already set and have never needed to adjust them. For plugs that do need adjustment, slightly bending the ground electrode to the correct gap is the correct way. Edited for clarity. |

When cars went to hei and 35,000+ volts, the plug gap isn’t very important, it’s going to spark. (Within reason)
My coin gapper sets them all the same, if off by a few thousandth, don’t care. You do index them, right? |

FFS.
I been using the wire ones for 30 years. I bend the c thingy until it's straight with the electrode and tap to gap. But fuckall, some nozzeleer will post a cool gapper tool and I'll just have to have one. Just like the cool tools thread, I have now a set of those low profile impact sockets with the wrench flats and a cable hose clamp tool.

Did the plugs in the Jeep about a month ago, use a wire gapping tool.
Only had to adjust one out of 16. Factory gap calls for .045. The old plugs were close to .080. Made a very noticeable difference. |

Buy a platinum tip spark plug because they are already gapped and you’ll never have to put another spark plug in that engine.

Lol,wow some of you guys are so up tight and angry this morning I bet if you shove a piece of coal up your ass you would pinch off a diamond.
I didn’t tell anyone to go out and buy this I’m just sharing what was given to me and I enjoyed using it. Made it much easier to adjust gap. Also everytime I’ve bought densos believe it or not gap is not at 0.43 Enjoy your weekend everyone & stay safe,?? |

Quote HistoryQuoted: You actually aren’t supposed to adjust iridium plugs from the factory as you’ll ruin them. Only if you're doing it wrong. If you have to gap a spark plug...reduce or increase...it is best if you don't increase the gap by prying open the ground electrode against the center electrode. One could probably go a lifetime with the old school "pry" method and not have a problem, but in particular with the tiny, thin iridium and platinum center electrodes, there is a possibility of damaging that center electrode. There is a cheap, simple tool that is usually attached to many of the simple plug gapping tools that grabs the outer ground electrode...the bent/angled electrode...and gently bends it up or down from the center electrode to achieve clearance. I do stress "gently". The ground electrode can be easily raised or lowered with this tool. It's not an arm wrestling requirement. It is recommended not to use that center electrode on any plug as a point of force to pry up the ground electrode. You'll get away with this more than 90% of the time, however. I just refuse to pry open a gap on an iridium or platinum plug using that center electrode as a pry or force point. |
