2009-2015 Audi A4 and S4 BIG MOUTH Ram Air Intake Snorkel

The 2009-2015 Audi A4 and Audi S4 are powerful machines, although they both produce a ton of heat. Heat is the enemy of horsepower. We took our expertise in dynamic pressure recovery ram ducts and applied it to the 2009-2015 Audi A4 and Audi S4 to give you the best bang for the buck mod for this platform.

Boost mass air flow with higher inlet pressures from a true ram inlet and smash your inlet temps back to ambient to keep your engine much happier. Keep your Audi breathing so it's working to its peak, make sure it breathes through Velossa Tech.

Designed in-house right here in the USA with the latest aerospace flow path engineering and design techniques, and backed by hours and hours of R&D, fitment testing and real world driving, we are sure you will fall in love with American made quality and engineering.

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 Audi A4 or S4 to stand out? The BIG MOUTH is the only ram air system for the 2009-2015 Audi A4 and S4 that allows you to choose from over 28 colors, giving you the added edge of customization, with over two dozen different variations available.

Installation

Installation can be done with basic hand tools. We supply all straight forward color instructions (downloadable below), backed with our Customer Support phone number to help guide if any questions arise. All hardware is always included (if necessary) in our BIG MOUTH Ram Air kits.

NOTE: Rain or snow do not adversely affect the engine once a BIG MOUTH is installed.

When people see that massive inlet through the grille, they'll know it's Velossa Tech!
