Like other hood scoops, The HAYS Ram Air’s the easiest to explain gain comes simply from providing cooler air to the engine. The Ram Air functions as a cold air intake, but then it provides additional benefits by altering the pressure of the air being admitted to the engine.

The HAYS ram-scoop tends to start small and then widen as it gets closer to the engine. This forces the air to enter quickly but then slow down. Slow air gradually surrounds the engine, with fast air continuing to come down the scoop, increasing the pressure. The high-pressure air acts like a supercharger would.

At higher road speeds, a properly designed hood scoop known as ram-air intake can increase the speed and pressure with which air enters the engine’s intake, creating a resonance supercharging effect. Such effects are typically only felt at very high speeds, making ram air primarily useful for Professional Racing.
