Do you need to gap these?

I always check, carefully. I have heard that you damage the contacts, but I've got a pretty light hand with a feeler gauge. That said, I've never had one come up gapped wrong in the last 10 years... These being no exception.

Not sure what you mean about no gap. But usually it is the big rubber disk (as seen in picture) that fails. When I took the old one off, the rubber was actually in 2 pieces (and the fluid inside made a mess pulling the mount out after it was unbolted). I do not think you need anything else as it is this rubber that always fails and none of the other parts (poor engineering IMHO).

These are trimmers so they come with a "zero gap". They are not outwardly adjustable, you'd have to take them apart and even then may not be adjustable. Im not certain because I haven't taken them apart but I wouldn't recommend it for warranty reasons. They come with guards that fit. Anyone looking for something more adjustable may have to upgrade to "clippers" with multiple guides or go with a different model trimmer.

No, when the mesh is zipped closed there is no gap at all. Now there's little gaps in the mesh were there could get a claw through. I like the a lot.

If you have an R/O systems, you will need an air gap. Otherwise, I do not think it is necessary.

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.

In my experience, that is not necessary. Really, it's a matter of what sounds better to you since the acoustics varies from one room to the next. If you crank these up, the sound is going to fill the room regardless.

They come pre-gapped, no need to gap them. I checked all of the gaps for my Hyundai Sonata to be certain (1.016mm) and all six were perfect.

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.

That gap is designed to let the air in to mix with the fuel. it is entirely normal. you may have to block it a little in extremely windy conditions.

They are gapped but you may need to adjust them a little depend on the manufacturer specs.

No, there should not be a gap. I would contact the seller and let them what's going on. I would read the reviews and product review before buying any item.

No. Should be pre-set. However, you really should check gap on all plugs you install into an engine. It is good practice, and you can note it as a reference for performance. You may wish to vary the gap based on your requirements for performance, power of engine, and the load you place on it. If you don't know, or have a stock engine, just make sure all the gaps are the same. Use the factory recommend gap, which as we said, should be pre-set. Don't reset it unless you happen to hit the head when installing, requiring a re-check.

Mine were gapped from the factory perfectly. I still recommend you check them before installing. Results may vary lol

No and you have to be very careful when you gap them because the electrode is very thin.
