Absolutely do NOT spray WD40 on new plugs. Keep the insulator virgin and clean.

The plugs will be fine for 100 years - why not?

I agree, the WD40 sitting for a long time could crate a fouled plug. Just clean dry storage is all you need.

There is a limit to how long you can store spark plugs and it depends on what vehicle you are storing them for, like these from 1913

Obnoxious seems to be the styling cue for modern automotive design.
