It is exactly true, lol.
But lets qualify it, so there is no confusion:
Stock engine with stock air intake system on North American sold production car/truck made in the last 30 years.
3rd party CIA properly installed will, for sure and absolutely, not add any horsepower or torque.
Production air intake systems are designed at 150% capacity, this allows for air cleaner to get dirty before performance is effected.
Air plenums are also designed above capacity and to minimize turbulence.
There are hundreds of anecdotal stories about power increases with CAI, red spark plug cables and glittered radiator caps, these have one thing in common, all tests on these have shown anecdotal stories to be "overstated", lol.
There is nothing wrong with CAI, or a new muffler, as long as you are doing it for looks and sound.
Waxing the car or truck would make it faster than either of those through.
