even though you replied to a post made over a year ago and the person is probably not on this forum, i'm testing you....
K&N has developed their products to make your engine run better by feeding it cooler, cleaner air and flowing better than a stock cotton filter. whether he decides to get a k&n drop in or a complete intake kit with a 360 degree cone filter, he will be helping the engine get what it needs to perform. their filters come standard with a very subtle amount of oil on them so it can grab any little particle that attempts to enter the intake track to the combustion chamber. oil in the intake is obviously not what you want to hear. but there's such a small amount, it's not going to do anything. these engines get more oil through the valve cover than they ever would with k&n's filters. the car's computer does not know if the filter is clogged or not. but it does know what the air/fuel ratios are. those are read by the oxygen sensors on the exhaust and it will compensate. i've never heard of anyone losing power because they installed an aftermarket filter. the great thing about these filters, whether drop in or cone style, is that you don't have to replace them every couple thousand miles, you just have to clean them using k&n's filter restoration kit, which has multiple recharges and is still less than replacing the stock filter after a couple uses.
