Hi, just bought a set of NGK Platinum plugs, and I think they need to be gapped. I got the gapper but don't know the gap our cars need.

I have the 94 Max GXE with SOHC

TIA

Um, I thought Platinum plugs came pre-gapped? The pintle (or whatever it's called) is too fragile to be pushed against in order to gap?

 

just to update myself, the gap was a bit too small. I had to widen the gap a very very tiny bit as per jbbons25's link

 

Correct. If the gap is off, always take them back and have the clerk find some with the spec'd gap. Turning it into a DIY gapping party it a great way to kill a new set of plugs. I learned this the hard way in my late teens.

 

You can gap them if you use the ground strap to adjust the gap, but the normal wedge-style gappers will damage a fine electrode plug, be it platinum, iridium, or whatever.

 

well ain't that some sh*t, the autozone guy knew nothing. Didn't even tell me to buy anti seize gel, I had to tell him.

I used this tool to gap it. I used a tool like this to gap my platinum plugs, hope I didn't destroy brand new plugs.

I do stand corrected!! Thanks for the heads up, man.

 

so is that tool okay to gap?

 

It could be, as long as you aren't prying between the ground and electrode. You can do it with a pair of pliers, just grab the ground strap and gently open the gap. Use the tool to check the gap, just not to pry the gap open.

 

ah good, I didn't touch the electrode at all. Platinum tip is way too small, so my sense were like don't pry there.

Thanks!

 

Good call

Yeah, they are very easy to break, that's why most of those plugs come pre-gapped.
