The Best V8 Stories One Small Block at Time
K&N's relevance to smaller displacement engines, most of which have air filters of huge CFM capacity as compared to the engine's needs, is marginal--they are aware of this which is why in nearly all of their literature you will see cubic inches used as a measure of engine displacement, and large block V-8's in the testimonials and sample calculations.

You only oil the bottom of the filter, the side that points at the ground. The air flowing though will pull the oil in the rest of the way. People get too happy and hose them down when it's not necessary. I've been sold on K&N's ever since my motocross/dirt track days. I've had my K&N filters completely clogged shut with dirt/mud/dust without a SPEC on the inside. Done it dozens of times, no problems.
Besides, a white paper filter would look like **** under my clear lid.
