Ford has finally graced our American shores with a Focus wielding the RS badge, and we couldn't be happier. We wanted to improve and upgrade a lot of things on this car and among those priorities had to be an intake. Our engineers have spent many hours in development, performing a plethora of tests and data collection. This Is a full intake, replacing every core component in the OEM system including the airbox and the intake pipe. Our kit includes a 3in, aluminum pipe that routes all the way to the turbo, with all of the necessary bracketry to accommodate a perfect fit.The airbox has a similar design to the stock airbox, facilitating an improvemed pressure drop with an open top, exposing the filter to more air and sealing the box against the hood, keeping it fully enclosed. This airbox uses the factory air inlet ducts, grabbing air right from the front of the car and the ports are surrounded with weather stripping to avoid movement. We have put this intake through hundreds of miles of road testing and countless dyno runs to ensure repeatable and reliable max gains of 12 hp and 15 ft-lbs of torque that is safe on a stock tune. Look at our engineering blog for details below! No cutting or modification to factory components will be necessary, this kit is a direct bolt in for the 2016-2018 Ford FocusRSand of course, this product is covered with the Mishimoto Lifetime Warranty
