Too many car enthusiasts are looking to get a cowl hood to dress up their cars, but only a few of them actually have a basic understanding of what it truly does. You might have a faint idea of how a cowl hood can maximize the engine's power production. But for you to really appreciate the hood, you'll need to learn a few things about how it works. Specifically, you need to understand some principles concerning fluid dynamics. Practically speaking, a cowl hood acts similarly to an airplane's wing. Working on Bernoulli's Principle under fluid dynamics, the cowl causes air to flow faster over your car's hood at decreased pressure. This means air gets drawn against the hood, not from it. The curved upper surface of an airplane's wing causes the same effect; the reduced pressure pulls the wing and the airplane higher. Real cowls have induction vents at the rear end, and that's where cool air is drawn into the engine. And when more cool air is used in fuel combustion, the engine burns the combustion mixture more thoroughly. That's how cowl induction works, and that's how the cowl hood can boost the engine's performance. Mind you, only a real cowl hood can deliver such an effect. You won't benefit from fake cowl hoods; those products will just end up wasting your money. If you want to reap the benefits of cowl induction, make sure you get a genuine cowl here at Car Stuff.
