do different brands require different gaps. I thought the gap is what was essential for making the best "SPARK" for combustion.

I guess the engine size wouldn't matter, huh?

Re: GAP Sign In

You should also stick with ac delco on those. Don't use a regular gapping tools on platinum or iridium plugs.

Re: GAP Sign In

If you buy the right plugs, you shouldn't have to worry about gapping them. I agree with DS, nothing but AC Delco on that vehicle.

Re: GAP Sign In

You can gap them, but there is a special way of doing it. You need a wire type gap checking tool and a way to grab the edges of the ground strap to make changes in gap. You don't want to get a tool on the precious metal portions of the plug to pry on it.

Re: GAP Sign In

these type plugs are "NEW" to my 56 yrs. of working on cars/trucks. have always used a "feeler guage" to check gap & a "slotted"/round type gap tool to "pry"-carefully-1 bit @ a time-to the proper gap.


how is it you use a "wire gap" tool to change the distgance from the grounding strap & electrode???


thanx.

Re: GAP Sign In

Again, platinum plugs should not require gapping.

Re: GAP Sign In

Suggests you are bargain hunting for plugs? AC Delco OE best and forget it for ages. If you find a plug not correct out of the box I'd take it back or another set. At least note which one somewhere.


Pics iffy but types of gap tools below. Wire type best and I say just check. If you adjust you risk messing them up.
