Which spark plug plug gapper do you use on your lightnings. The tapered edge or wire gapping tool? I am in the process of gapping my plugs. I have both of the gappers and I am wondering which one is most accurate.

 

Wire or blade feeler. The wedge will damage fine wire electrodes, however still works great for Champion plugs that go in lawn mowers.

 

Yep, I learned that the hard way. Had 6 Denso plugs gapped and changed and while gapping the 7th, I broke the tiny little electrode off using a wedge type guage. After cussing and screaming for about 10 minutes, I took the other 6 out and put TR-6's back in. That was back when it would take me nearly an hour and a half to change the plugs.

 

Thanks for the response guys, but which one is more accurate because both give different readings when gapping the plugs?

 

Like MOP said, the wire or feeler guages work good.

 

 

This is the one my friend has. He used it today to do a spark plug change on my truck. Works great!!!



You can buy them here Jeg's

I'm the friend above. The one above is very nice because in addition to getting an exact gap, it keeps the entire electrode parallel for a straight gap across the plug, not tight at one end and loose at the other.

Those are from Jacob’s Electronics and you can get them several places, as mentioned Jegs, Summit, etc…

 

Yep, I owned a speed shop in the early 80's and I was their first dealer in the Sacramento area. Had some cool ideas and I've always kept this tool, works very well.

Cat's out of the bag now!!!
