I have a stock Autolite 2100 carburetor that is rated at 240 CFM.

I bought a Purolator Classic Round Air Filter A30057 for $7.59, at Advance Auto Parts that is an "Exact fit for your 1963 Ford Falcon".

But, ... the air filter is rated as 120 CFM.

Why is the filter only rated for half of what the carburetor will draw?
I would like to have a filter with a capacity that matches the carburetor.
When I bought my car it had a 500 CFM four-barrel Edelbrock carburetor and an aftermarket "high performance" air filter cover that contained a NAPA Silver filter, Part No. 22095 O.D.: 13.875”, Height: 3.087”. As an experiment, I tried putting it on my Autolite carburetor, but the center stud was too short. I bought a NAPA 6037 filter (Wix 46037) with the same O.D.: 13.875", but with a lesser 2.64” height and it fit.

Unfortunately, I afterwards found that this filter is rated for 215 CFM.

215 CFM is an improvement over 120, but I am still looking for a filter that will get me to at least the magical 240 CFM.
