A few weeks? More like a few hours. Do you really have two filters because you think it takes that long?Be careful when cleaning it. Buy two filters, use one, then swap in the second filter when you clean the first one. You need to let the fresh oil sit for a few weeks to cure and thicken on the filter so it won't get sucked into the MAF.
We've been through this before, you and I. Yes, it takes weeks for the oil to cure. I'm not talking about letting it soak in, I'm talking about letting the esters evaporate. All oils do this over time, that's what makes oil-based paint "dry out" even though there's no water in it to start with.A few weeks? More like a few hours.

I've had mine for about 20,000 miles, cleaned it once a little while ago and it's cool, good investment.
