Joe,
You are correct. I used that website to find the filter. Unfortunately I’m driven by size concentrations, as I’m fitting a paper/foam filter to an old school oiled mesh housing. I will most likely go with a K&N when it becomes available (out of stock now).
I emailed Wix the question of why the CFM ratings are so low as compared to carb CFM. The filter you gave for a Mack truck is only 275CFM. Don’t know Mack trucks but surely that suck more than 275CFM. We shall see what Wix has to say. Thanks.
