C Canadian_JOY Well Known Member May 22, 2023 #4 I have used plugs that were verifiably 40+ years old. No problems with them because they were stored well... not dropped, not rusted.

M meloosifah Well Known Member May 23, 2023 #5 I just installed a spark plug from 1982 in my 3 wheeler. As others have said - you can’t drop them or leave them in humid environments but otherwise they are virtually eternal.
