Something very cool is happening here. Real cold air comes from OUTSIDE your car - not ANYWHERE under the hood. Unless you have a supercharger or turbo, nothing rams that air other than a true NACA-designed inlet duct. The DGM P3/P5 ram air hood does this - and does it with style! Of course, the hood is 100% hand crafted carbon fiber, with a completely finished undertray. It comes complete with an AEM ducting and filter package, and our 1 year warranty on fit and finish.
