Please don't kid yourself into thinking that the K&N is giving you better results. The only think that it's doing is making your motor and throttle dirtier.

You are actually wrong... Paper filters let very fine dust right through that coats the inside of the intake tube and can easily be seen when replacing the filter. An oiled media on the other hand catches all that fine dust and traps it. The inside of the intake tube on my Tacoma looked like it was removed from a brand new truck, and that was after 50,000 miles without cleaning the K&N. Trust me, they work, even in harsh conditions...

As for the MAF, I have personally over oiled a K&N filter and caused a CEL. But cleaning the MAF is SIMPLE (using CRC MAF cleaner, don't EVER touch the element with a q-tip) and disconnecting the battery resets the light. No harm done.

Compared to a stock paper filter, K&N's are better in every way...

It's an approved cleaning method on Identifix, unless someone isn't born with dexterity and nerve endings, and is real sloppy.

Paper doesn't invite gunk buildup on the MAF quite as well, causing a 10-20hp loss at the wheels instead of about 1hp gain at the wheels, if you're lucky.
