which brand of cold air intakes

Someone needs to come up with a system that puts the dry high flow filter inside the grill, down low maybe. What about inside one of the front fenders ? Cowl induction ?

That’s not 100% correct, some cai require a tune because it leans out the afr too much. Why is that? Better/more airflow? Take the air box intake tube off your TB and see how well it will idle or run, not very good im
betting because it’s so lean but how can that be if the TB is the restriction you just claimed it to be?

Does anyone think Ford would not redesign the air box if they could pick up an additional 1 mpg or add another 15-20 HP?
I think it goes without saying that these systems are well engineered to be as efficient as possible. I just don't buy all these big increases with aftermarket CAI's.

I read this years ago, don’t know if it’s true or not. Let’s just assume a CAI flows more than stock. When you put one on a vehicle and immediately run it on the dyno the computer hasn’t adjusted for it yet. This makes the engine run a little lean. Most vehicles run a little rich at full throtle so by going lean they make more power. So the immediate first dyno run shows higher numbers. Take the vehicle and drive it a little bit and dyno it again, your right back where you were.

Everyone needs to lay off the exclamation points today. Cheese and rice. 
The reason I don't like aftermarket cai, regardless of any minuscule gains in peak hp, is they let in a lot of trash. Wipe your hand along the inside of someone's intake tube after they've run one of these high flow filters for a while and see how nasty and gritty it is. My buddy had a K&N and he literally had sand inside his intake that got past the filter.

Mfg’s are also constrained by various limits with packaging, noise, etc.
The aftermarket can push those limits and eek out a few more HP. You have to look at it as a part of the puzzle. The OP is looking for a bit of improvement and with the typical intake/exhaust/tune puzzle he’ll be maximizing the benefits of all the parts as a whole.
He never asked for anyone’s opinion on aftermarket vs stock...some people just feel compelled to preach even though their opinion was never asked for in the first place.

So everything on our trucks is optimized for best performance?
Come on people, there are compromises in every part of our trucks, a CAI adds airflow and noise, that compromise is a different one than the convoluted intake path on the quiet stock intake.
I see the bar keeps moving on what these intakes do, they either do nothing, (impossible, they do something!), or they add airflow, which messes up the truck somehow, or they cause the truck to not adjust the mixture, which smacks of ignorance, or they add airflow via cleaner airflow path, and he truck adjusts (bingo!), or you can add a tune, which works in conjunctions and adds horsepower.
Cant pretend one and not the other.
Appliy your anti CAI arguments to any other point on the truck, and reflect on why some trucks are faster than others, could it be the modifications and or bolt ons on the truck?
