Please take this as a constructive concern. People on here tend to get very defensive and/or take things personally.
There are a lot of very good in-line, billet aluminum, filters available with "canister" type elements. Holley, others at Summit Racing, Aeromotive (whopping 60 sq in of filtration area with a microglass option), etc. If your current product's configuration indeed matches the picture, I'd strongly consider something with more margin in the future.
As mentioned, filter surface area isn't an issue until it is. Then it is probably too late.
Be safe, Sir.
