my 2003 cavalier plugs need to be gapped at .043,however i can`t find a tool that will do this.My wire one goes fron .040 to .045.any suggestions on finding a tool with .043.
Thank`s
 
i looked today,the only one is the coin type, and i know that those are no good.
 
Oh.. I'm guilty.. that's what I have.

NAPA you can get the good one. Also, in the tool isle in AZ they used to have one as well. Though its plastic, so I dont like it as much as the one I got from NAPA.
 
Yeah, that`s what I will do.I was hoping some knew on a specific tool.
 
With a blade-type feeler gauge, you can stack 2 blades if needed. I recently bought & gapped a set of plugs for the Dakota- still haven't installed 'em yet. NGK recommended gap for these "V-Power" plugs & my application- .044". My largest "crooked round wire" gauge is .040. Got out an old blade-type gauge that has *Lots* of blades- but still nothing for .044. So I stacked .021 & .022 for .043- close enough, & 5 out of 6 plugs were a just-a-little-snug .043 from the factory! #6 needed only very minor adjustment- actualy didn't need it at all, but I did it anyway. Old habits die hard!

FWIW- all NGK copper core plugs I've ever used & checked for the Neon, a friends truck(302 Ford), the mowers, and now the Dakota, have all had gaps so close that, even though I've adjusted a few, really didn't need to adjust any of them. Wouldn't surprise me if a set was gapped just right for your engine. Cheap too, just under $2/plug at O'Reillys.

Of course, you can just use your current gauges as .040= Go, but loose, & .045+No Go-at all! It'll be plenty close enough, don't worry.

Pregapped for what engine? The mfg. of the plug has no idea what the end user is going to use their plugs in.

BTW, so many say the coin tool is no good, well its worked for me for 50 years with no problems, just know how to use it, and yes I know how to measure items with close tolerances, I was a tool & die maker by trade till I retired.
 
I've always used the round coin type gauge too. For over 20 years here and that is what my dad showed me how to set them on as well. Heck, I think he has had the same coin gauge for probably over 30 years! I know I've had mine forever too! I think it's the first and only one I've ever bought.
 
I've also thought that the round wire gapping tool was best for conventional plugs but couldn't be used for platinum tabbed plugs. For platinum you need the coin type. I guess you could just use the coin type for both if you want.
