Spark plug "best by date"?

[brabus3.6]

Quick question, do new spark plugs get worse with age? My intuition would suggest not since they will not significantly corrode and are inorganic. Sparks in question are a lot of Bosch H6DC sparks which my Brabus uses but they are shown in the old yellow Bosch packaging. Any difference guys?!

Keep them in the fridge and rotate them in the package by 180 degrees every 6 month. That should keep them fresh for later consumption.
Here I thought April Fools day wasn't for another 4 month.

Is this an early April fools thread?
