For many years now, ram air hood scoops were put in place to shovel in more air into the intake system causing an increase of performance by horsepower. This new Chevy Silverado HD hood scoop is also designed to create better performance, but not by forcing more air into the intake system, instead, the hood scoop will help create a cooler engine compartment for the engine which can also help create better performance.
These trucks are designed for towing/hauling, four-wheel driving activities, long drives, withstanding major mileage while still performing well. Whenever an engine can run cooler it will always perform better. So when an engine is under constant stress, like these Chevy Silverado HD trucks spend a lot of their time under, it makes sense to want to keep that engine as cool as possible for all of the time that it is performing any type of activities.
So just how much does this ram air hood scoop actually help?
The ram air scoop will take in 60 percent of all of the cool air that will enter the engine compartment. The other 40 percent of air will come through the space behind the front bumper which is designed to take on the engine compartment air funneling responsibilities even if the ram air scoop gets blocked up.
The ram air design features a 90-degree angle which is capable of catching large droplets of water (rain) and small debris keeping out as much moisture and crap as it can to ensure that as much clean and cool air gets into the engine compartment as possible.
All and all, the scoop not only looks pretty cool, but it is more functional than a lot of ram air hoods we have seen in the past. Let's face it, some ram air hoods we have seen though the years hardly created noticeable extra horsepower and some of which we've seen weren't even functional.
I have yet to hear any official statement if GMC will have the same ram air scoop on their HD trucks, but one would imagine they will follow suit.
