When I wash them, I just make sure to give them a thorough clean, thorough dry, and then lightly spray it with regular oil. Simple as that.

I am sad to hear that obviously they have dropped their quality, I don't remember them being that bad.
I am just about to get an Uprev tune from an experienced tuner and his thoughts were that I wouldn't see much benefit from a major intake upgrade (eg Stillen Gen II) and to just replace stock paper filters with the K&Ns since in his experience they have been a really good product with good results that are cost-effective.

Saying that, if they are overloading the filters with oil at the start then maybe he's not in the loop with what happens after a few 1000 miles when the oil starts to get pulled through the intakes.

So it makes me wonder whether you should clean all the excess oil off of brand new K&Ns right at the start? In fact, I think someone earlier in this thread said the same thing?

I currently run them at two cars at home, and none seemed to come with too much oil from the factory.

You can run K&N filters dry. Not sure if its a good idea but there are plenty of dry filter options out there.

Having said that, if worried, a light oil coat is all you need. Will that do much and are you wasting money on the oil kit? or just keep it dry.

Perhaps the dry filter options use a tighter weave or other materials to achieve the same thing. Not sure.

Hers one example. Looks the same as a KN but again, maybe different materials:
