 Put the filter on a Buzzsaw/Log splitter powered by a 40 horse VW engine. So far it is working great. Love the product..

 I asked KN for information and what did I get ???  A real answer, a technically based answer, not a quick guess... I got science, I love it.  Here is the message I got back.

Thank you for your interest in KN products. This air filter, HD-0300, will flow more than enough air for your application. Your motor, spinning at 6200 RPM, at 100 volumetric efficiency is capable of pulling 145 CFM. This filter will flow 197 CFM before 1.5 in/h20 restriction.

Frankly I expected quality from KN and was impressed with a data based answer.
