yes if some clown dumps a whole bottle of oil on a K&N filter ,that could cause problems to the sensors on a modern vehicle. HOWEVER they come with directions.
i will now read direct from the K&N air filter oil recharge can
"K&N gauze air filter oil:
fomulated especially for K&N gauze air filters
red uniform color of oil indicates a properly oiled filter.
when applied, the oil will soak evenly into the cotton pleats thus creating a SUPERIOR tack barrier for dirt- yet allowing maximum air flow"
what more needs to be said?
get er done
Piglett, my point is that on a modern computer controlled vehicle a K&N- AFE - or any other filter does not increase performance or MPG's on their own. The computer is only going to let so much air into the combustion chamber. You can run a OEM filter till it looks like crap and there will be no difference in performance, until a insufficient quantity of air gets through the filter. The seals around the edges will harden and crack, letting air in long before the media is so clogged that enough air does not get through. We (myself included) are just victims of slick marketing, (companies wanting to sell you something) and our fantasies of a couple of horsepower or MPG's. And yes there are a lot of clowns in the world(not specifically you).
Back in the days of carbs, performance air filters made a small difference in the amount of air that entered the combustion chamber. But they also leaned out the fuel to air ratio, and if the fuel mixture was not richened, the engine could suffer damage from running too lean, over long periods of time. Ask any motorcylcle mechanic who worked on 70's and 80's Japanese motorcylcles, and the owner put a high flow air filter and low restriction exhaust on their bikes and didn't adjust the mixture richer(mixture screws had EPA caps/seals on them), soon (5 or 6K miles) had burned exhaust valves from running so lean. Ask me how I know.
Here is a favorite quote of mine regarding folks who like to modify their vehicles from manufacturers OEM parts or recommendations.
A modifier is an individual who enjoys playing Russian Roulette with their vehicles, because they cannot stand being told what to do or use, by the manufacturer who warranties vehicles for up to 100,000 miles.
