Here are some links to some previous testing,

   • Mopar 6.4 392 Hemi cold air. Initial ...   Mopar CAI

   • Legmaker True CAI vs Hellcat Air box....   Le0gmaker CAI

In this, admittedly, long-winded chat I'm discussing my thoughts on cold air intakes in general. This is by no means "all inclusive." Also, keep in mind these videos are almost always done in one take so there may have been a thing or two I may have missed. In some cases cold air intakes (CAI's) do work but well, but this is a perfect example of caveat emptor, or in plain English, buyer beware. I don't want to discourage anybody from being involved in their car, truck or whatever it is that you're working on. I simply want to bring to light some of the areas where cold air intakes can show a gain, but in reality not yield any real real-world results. I say all of this with a 20-plus year background as an automotive enthusiast, someone who has worked on cars for practically my entire life. I'm sharing this because it frustrates me to no end to see Wild claims about aftermarket parts then in reality don't show any true to life gains or are misleading at best. I have spent countless thousands of dollars in this hobby testing, tuning, blowing up and fixing all different platforms. It's safe to say this knowledge is based only on my experience, yours may vary.... you get the point....
