General statement...
If these oil type filters were so great, why dont you see the high dollar real world working diesel equipment running them (think , cat, deere, case, etc)? That's where you have real need for horsepower and reliability for expensive equipment and maintaining wet filters is a nightmare.
Quoting airflow is questionable because you can only pull so much air volume on a naturally aspirated diesel and a turbo can only push so much air into the engine. The engine takes what it needs.
You answered your own question. Dry filters work as well and they're throwaway when dirty. I like reusable, throwaway is easier to service.
"Naturally aspirated diesel?" Who even uses them now?
A turbo forces air into the engine and the engine uses what's it's given. Diesels can take a lot of air.
You are sadly mistaken if you can clean a depth loaded oil air filter and attain the same protection of a dry element. Reusable is not the time to think you are going to get better performance. Oil bath filters went away on equipment in the 1950's for a reason.
And there are a lot of naturally aspirated engines on many pieces of equipment. You are only thinking of your pickup.
Yes Turbos do push air in, but a lot of it goes out the waste gate too. The CAC adds a lot of air restriction so you get diminishing returns and the engine only takes what it pulls it. Its not an infinite volume to pressurize and they regulate the stochiometric burn to hit emissions targets.
Your saying you get "25 HP more" is a loaded marketing lie. If you got 25 HP more power out of the engine, you would boil your cooling system. You may be getting 25 HP more than a falsified heavily restricted and biased air filter test to make the oil filter product to look good, but the cooling system was qualified to a dry paper air intake system. You can get any more cooler or fan performance to cool that magical 25 HP that shows up from no where.
