No. The edge is of a material and thickness to fit directly and seal.recently acquired a k&n air filter, from a crashed bike..............
question is this.....does the k&n filter require the same rubber gasket around it as the stock filter, when installing
????? I thought oil was needed only after cleaning.You don't have to oil them every couple of weeks to maintain the filtration.
I'd guess that a paper element would soak up the water (that's what paper does) and prevent any air from getting to the engine, giving you the choice of waiting for it to dry, or riding without a filter. And the oiled filters generally filter BETTER after they have a layer of dust, since the fine particles have a tougher time finding a pathway through, although the flow tends to fall off proportionate to depth loading. I'm guessing the trick with cleanable filters (like the K&N) is to clean them without getting dirt on the inside of the element, then getting a uniform layer of oil (not too heavy, not too light). An OEM filter (assuming it has a gasket on it) is pretty fool-proof, by comparison.This is not a concern for you as you don't ride off-road, but if the bike were dropped in a stream a paper element will prevent huge mounts of water being sucked into the motor. Gauze, well,... it'd be ugly.
A heavily pleated paper filter will pass plenty of air and will only become a deterrant when dirt clogs it. An oil moist gauze might pass moreair in comparison than paper but will also pass more fine dust once the oil film is dirt saturated.
