Are air intakes on a stock truck REALLY doing anything for you?

Any filter design that allowes hot air coming off the radiator is a problem on a street driven truck.
Open air filters give lots of blower wine. This may be bad or good depending on your point of view
k&n panel filters will not increase your power but they can be cleaned often. A clean k&n makes a lot more power than than a dirty stock filter.
A ram air set up will give very little if any added boost from scooping air but they will scoop in lots of water, bugs, leaves sand ....if driven on the street.
Air intakes must be at least one 3" dia tube. 4" can be done but is a challange to get thru to the front of the truck. A few people use 2 - 3" tubes.
Most of the posts are based on opinions of drag racers that are running on a cold motor, before the radiator gets to 180 and opens to cause these issues. I drive on the street using obd2 readers, inch of water vaccum gauges and accelerometers to get data, not noise and a$$ometers for an opinion.

I'm not saying that sooner or later the K&N airfilter won't showup, but with just a chip it doesn't do much.
