The Data is suggesting you will get more air flow in a ISO test bench session(not directly relating to a % increase in BHP though), and you will get more dirt and it will clogg up fast and therefore performance will reduce rapidly.
That is exactly my point, the K&N will flow more air on a test bench, and it will let in more dirt, but the air flow through the OEM filter is more than enough for the engine in stock configuration.

I think I can count on 1 hand the number of original parts left on my car but two items that I have never seen bettered by any aftermarket products are the original air filter and the original oil filter.
