I installed a JWT cone a little less than 2 months ago and noticed today (after reading TylerCanada's remarks about how his cone oil got washed away by carwash/rain) that my cone has faded noticeably since day one. It almost looked as if the blue oil was almost all gone (when new, it was blue, today it was blue-white).
I decided to do some testing, to see if carwash/rain really does get the filter wet. I went to the local coinop and blasted the driver's side hood section with the high pressure spray and checked afterwards - only a few drops of water got on the cone, not even close enough to wash any oil away. When I say a few drops, I mean just a few drops, enough to see water spots on the metal part of the cone, but thats it. So, my conclusion is that neither carwash nor rain washed the oil away, and the JWT cone just comes very very lightly oiled (and probably requires earlier service, for the first service).
K&N does note that the dye on the oil does fade over time, but the oil remains. I have a JWT cone on my Maxima and even after 10,000 miles the filter is still as red as when I oiled it, so I don't buy the fading dye idea.
I picked up a K&N recharger kit at Autozone (just $10) and cleaned/reoiled my filter tonight. Its red now.
