Do they need to be gapped?

No they say not to and I did not gap them pre gapped for the car You buy them for

No they do not need to be gapped. The spark plugs come with a tube cover protecting the threads and electrode incase the box is dropped.

They came pre gapped. However I did check just to verify and be on the safe side. I didn't need to make any adjustments.

Yes they are....but as you know handling them in shipping etc. may change the gap. So be sure to recheck it.

Mine were pre gapped for my 2007 honda civc lx . 12, 000 miles after changing plugs no problems noticed better performance and fuel economy.

Yes, the gap on these is set during manufacturing at .040. The gap is not intended to be modified. Always a good idea to check first, but I've never found one of these to be incorrect.

i recessed mine. whether or not it has to be is best asked of the manufacturer or vendor.

Not necessary. We just applied paper over them. They paper has decent strength to hold up. However, if you expect kids or other objects to run against on a regular basis, then the paper might pierce and tear on the gaps.

No.. I used super glue and a clear silicone to fill in any gaps. You need a steady hand. Good luck

They are solid - and are supposed to slip into place. They just left big gaps.

It will be a gap. they are visually rectangular but due to manufacturing processes (hi temp) sides got a little curve and looks like hand made. Just allow some space between them.

They are gapped very close, but I always check with a gap gauge any new plug for any application.

You could leave one of the two halves of the green tabletop off... That would create a gap. Otherwise, no. The two boards are pretty much flush.

They are exposed on each inside corner, however, when closed, the leather overlaps just a little so they are fairly well protected. But you are right, there is a gap of about 3/4 of an inch. I have not had any issues with it.

Trying to understand your question, I assume you want to know if the plugs are already adjusted. The short answer is no. Even if they claimed to be adjusted, I would check the gap to make sure it was correct for my vehicle.

Mine sits perfectly, no gap. I'm guessing a batch of their production went bad as i saw some similar comments here lately.

Yes, I had no problem with height. They won't fit across perfectly but you can spread them out to make them look good with minimal gaps.

No gap, they fit perfect. They show a yellow reflector in the turn signals, but mine came all black.

Yes. Mine fit with no gap. Even with no gap it is not a tight air barrier so with a gap -- that would be most unpleasant.
