Old filters?

[matria]

Hello everyone

Surfing through ebay, I see air filters that are advertised as NOS or say it's been sitting in a garage or on some store shelf for 20 years or so and it makes me wonder if there is a shelf life for these filters. This would also go for oil and fuel filters and others. I don't know if the filter material would start to break down and disintegrate. Other then technology changes, is there any reason not to use NOS?

I saw those to. I don't think that they fit a Z , any way I dont want to store the things and besides I am satisfied with the brand I buy. Some things you can save $ on but oil and filters are not it.
