I have found a marking on my original plug caps that say 1k and the little ohm sign. I have a new set and they say 5k. Everyone I spoke to said it wouldn’t make a difference. I may have to get some of the 45-degree plug caps for my Euro motor so the 5k may be mixed with 1k spark plug caps.

Can anyone explain what should be considered?
