[Healeys] (slightly) OT: K&N air filters

[Bob Spidell]

Have a set of K&N air filters on my BJ8. These are roughly the same dimensions as the stock grasshopper-stoppers--about 2" thick by 6" diameter--but engulf air around the periphery instead of through the large flat surface. One of them has shrunk! It now fits loosely in its 'frame' (for lack of a better term). 

I can see the cloth portion shrinking--somehow--but can't understand how the plastirubber rim around the edges could. It's not a minor amount either--about a half-inch in diameter. The other is still original size and fits snugly in the 'frame.' Anyone seen this happen? I guess I'll have to order a replacement, but this baffles me. Some combination of heat and pollutants (oil, gas fumes)?
