I am currently using a K&N air filter that is 12.5" OD, 11.0" ID, and 2.75" tall. I would like to gain some hood clearance and I have found a filter that is the same OD/ID but it is 2.12" tall. Is there a way of checking to see what cfm or hp rating an air filter size might have?
I just want to see if down sizing the air filter won't hurt my 340 setup.

Thanks
