Well the turbulent airflow idea is not mine, these are facts. You can look them up. It comes from the same concept as porting and polishing the runners on heads, port matching and polishing intakes, even porting throttle body spacers, and old school carb spacers. But you are correct about turbos. All 5.0’s are n/a from the factory unless you have a factory built Roush/Shelby or any other dealers that add on turbos or superchargers that are backed by the factory warranty. mine is a regular n/a 5.0. Forced induction is a different ballpark.

please explain how lasted EFI systems work....
Also since you can only selectively read, I asked for opinions on brands of CAI not how EFI works. I have no idea how you got that out of my post. I can type it slower and be more descriptive or maybe I find a link online that will read it aloud for you, since you don’t understand my post. Let me know if I can I help you!!! 😉
There has to be something aftermarket cai’s do. Whether it’s positive/negative is debatable.
I say this because I have put the AEM “cai” on my old 2.7 and now my 5.0, and both times my MPG’s improved. Same routes, same driving habits, but increased MPGs.
also, they change the sound quite a bit (also debatable to be good/bad) so there has to be something changing right? Even if it’s 5hp, that’s 5 more than the stock truck next to you

There's no doubt a good CAI can improve... something... but that's only if the existing intake is poorly designed/room for improvement. The current F150 stock CAI is a pretty darn good system especially for stock. Just not much can really be done to improve on it.
In an independent test I'd be willing to bet there's no way you're getting an additional 5Hp.
As far as recommending one.... I guess it would be the one that brags the most.

With the fuel tables in open loop, and closed closed loop, the PCM tries to keep the A/F ratio at 14.7 (stoich). This is the reason going from a dirty air filter to a clean one doesn't improve MPG. Same rational with an aftermarket CAI, increasing the intake diameter doesn't increase airflow, the airflow velocity is decreased. The only advantage you get with an aftermarket CAI is WWR (Wallet Weight Reduction).

OEM intake! I was giving technical reasons why there is no advantage to aftermarket CAIs.
