How It Works

As a car moves through the air, the air pressure directly in front of the bumper increases with the square of speed. The BIG MOUTH is strategically designed and positioned for maximum air pressure recovery. Basically, it feeds your current intake with higher pressure air. It is the same concept as driving below sea level where the air pressure is higher, except you are able to generate higher inlet pressures with a properly design ram duct such as the BIG MOUTH.

Increasing the inlet absolute pressure to your engine has profound effects on performance. Increases in air mass flow, reduction in wastegate duty cycle (for turbo vehicles) and reduced inlet and charge temps are some of the benefits of running a properly designed ram inlet. On top of all that awesome performance comes the BIG MOUTH growl and sinister stare, it sounds and looks great!
