Want to add more aggression to the look of your Subaru WRX or STI? Look no further than the Velossa Tech Big Mouth intake, the go-to mod for any induction set up.


Bolting on to your existing stock or aftermarket intake, your new aggressive look also comes with a boost in performance. That’s right, the Velossa Tech is a ram duct that we’ve engineered to specifically suit the Subaru WRX/STI. Not only is the fitment perfect, it also maximises performance by providing better overall mass airflow to a stock, tuned or highly modified engine.

In terms of customisation, our latest Generation 4 Big Mouth Ram Air Intakes have got you covered. With over 28 flare colour options, our Gen 4 Big Mouth’s feature removable flares, meaning you can effortlessly change the colour of your big mouth or easily replace a damaged flare by unscrewing a couple of screws. No need to fork out extra money for a brand new kit. 

For a really wild look, add some LED action to your Big Mouth with our Lit Flares.  They've been engineered to easily bolt on to our Generation 4 Velossa Tech Big Mouth bodies.  

Designed and engineered in the USA, to ensure we produce the highest quality products, Velossa Tech has utilised the latest aerospace flow path engineering and design techniques, a multitude of hours in research and development, fitment testing and real world driving. Plus unlike some competitors, all our Big Mouth’s are finished smooth for maximum air velocity. No cheap-looking 3D printed ridges.

Each Subaru WRX/STI Velossa Tech Big Mouth Intake Kit includes:

  • An optimized convergent duct suited to the Subaru  
  • A flare of your chosen colour
  • All installation hardware
  • Two layer UV protective coating for sun protection against colour fade

How It Works

The BIG MOUTH is strategically designed 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, however, due to the Big Mouth’s accurate ram duct design for the Subaru WRX or STI, you are able to generate higher inlet pressure.

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, the BIG MOUTH’s growl and sinister stare sounds and looks great!
