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!

Customization

Want your 2015-2021 Subaru WRX/STI BIG MOUTH to stand out? The BIG MOUTH is the only ram air system for the 2015-2021 Subaru WRX/STI BIG MOUTH that allows you to choose from over 28 colors for either the body or the flare, giving you the added edge of customization, with hundreds of different variations possible.
