Those who understand how an engine functions and airflow vs. engine speed, would know immediately that the dyno data is bad data. If you don't understand how an engine functions, then yes I can see where you could be duped by bogus dyno data or performance claims like 30% more airflow. As a trained professional, specifically in the area of advanced engine design and dyno development, I post technically accurate comments to help people better understand how an engine actually functions.

BTW, you misunderstand the bad dyno data. There was not a 13 WHP gain across the rpm band. You could have completely removed the air filter and not gained 13 WHP or even 13 HP anywhere in the operating band.

How about you provide accurate dyno data where many brands of after market filters were tested using only engine dyno.

Thanks.
