Designed specifically for the new Focus RS platform. State of the CFD simulated ram inlet designs are standard for all BIG MOUTH products.

Use the forward motion of your car, turn that motion into pressure. Increasing the inlet pressure to your turbocharger has profound effects on performance. Increases in air mass flow, reduction in waste gate duty cycle and reduced inlet and charge temps are some of the benefits of running a properly designed inlet. This set up is designed to receive a direct feed of cold air from outside the car than consume hot air under the bonnet that is heated by the engine.

The BIG MOUTH ram air intake will work with your stock Ford Focus RS intake system or any aftermarket intake system.
