Rara, those graphs appear a bit odd to me. Kind of up & down. Seems odd that KKM would be equal to K&N then drop down only to be slightly higher at the end. Not sure it was not artifact or another explaination. In my own comparo of KKM vs a different larger K&N I found the graghs were almost identical until 6500-7000 RPM were K&N was better but only by about 2 HP. For all intents and purposes "a draw", though possibly an indication that at higher flow rates K&N may prove better?
Brentos, flow data interesting. Others have shown removing stock airbox with K&N improved power but first Ive seen stock "open" paper filter comparable.
