Just received a Pipercross panel filter for my LCR225. The silly question is, which way up does it go into the airbox? There's no fitting instructions that I can see and couldn't find anything on the Pipercross website - should the grille be facing up when I drop it into the airbox or the foam side?
Also, I thought this filter would be an oiled type. Certainly there seems to be some sort of oil on it, I could feel very slightly oily residue on my fingers after taking it out of the box, but the box has a sticker on it saying "Dry Filter - NO OIL" on it. Does this mean it doesn't need oiled every so often, or does it mean that I need to buy some oil and put it on the filter before I can install it?
