Function

• Cooler air is less dense and allows the engine to function more efficiently. This greater efficiency can have various effects, including an increase in attainable speeds.
  
  

Expert Insight

• Dr. Philip Ganderton of the University of New Mexico states that the larger the hood scoop, the more effectively it will cool the engine. You can also couple a hood scoop with a fresh air diverter for an even more substantial effect.
  
  

Considerations

• Many hood scoops are intended for aesthetic purposes rather than functionality. These scoops will not alter engine heat because they are not connected to the engine. Check the packaging to ensure the scoop you purchase will work effectively when installed.
