Canadian Group Buy: 2016 Focus RS Ram Air BIG MOUTH Intake

Starting at: $169.00

Many of you already know about the BIG MOUTH and its popularity among performance enthusiasts. It offers true front facing ram induction and endless customizability. Performance meets aesthetics.

In laymans terms, a ram induction intake will use the forward motion of your car to produce positive flow. Just a reminder, as a result of the nature of ram induction systems, gains are not seen on the dyno but rather on the street when the car is in motion. We saw anywhere from 0.3-0.6 lbm/min increase in mass flow depending on your mods and vehicle speed. You will also notice an AUDIBLE change in your engine, it will sound like the scream of a million tornados. As well as drastic reduction in inlet temps and charge temps. Your turbo will thank you and will pick up some top end!!

Designed specifically for the new Focus RS platform. State-of-the-art CFD simulations and rigorous flow analyses are standard for all BIG MOUTH products.

The Focus RS is no exception.  The Focus RS BIG MOUTH ram air kit features an industry first, customizable airbox seal. This seal partitions the airbox from the engine bay, allowing the BIG MOUTH to feed higher pressure air into the airbox without losing air mass or pressure to the engine bay. During idle conditions, your airbox will not ingest hot engine bay air. The seal comes with a soft rubber strip that mates to the entire perimeter of the open hex area of the airbox. This creates the air tight seal and allows your BIG MOUTH to function as intended.


If you wish to buy just the BIG MOUTH duct and do not need the seal (if you have an aftermarket closed airbox), select NO in the drop down menu for the airbox seal option.

Choose the colors of your BIG MOUTH body, inlet flare and seal. Pop the hood and everything matches as if it was OEM! If you were looking for that best-bang-for-your-buck modification for your Focus RS, this is it. Get aerospace level performance, award winning design and a proven track record, don’t look back.

If you live in Canada, NOW is the time to get the BIG MOUTH. We will be offering you an exclusive discount for the group buy and shipping will be domestic for participants thanks to the kind folks at RaptorRacing for hosting the distribution. 

With 15 different color options available for either the body or the flare, you have 225 different color combinations to choose from!
