Description
Mishimoto’s MMAI-RS-16P is a full-replacement performance air intake built specifically for the U.S.-spec Ford Focus RS, swapping out every core piece of the factory intake tract—airbox and intake pipe included—for a purpose-engineered 3-inch polished aluminum pipe and a redesigned airbox. Backed by hundreds of miles of road testing and dyno validation, this cold air intake system delivered repeatable gains of up to 12 hp and 15 ft-lbs of torque on a completely stock tune, with no cutting or modification to factory components required.
As a dedicated air intake system rather than a simple filter swap, this kit is engineered to lower pressure drop compared to the restrictive factory setup. The redesigned airbox retains a stock-like footprint but adds an open top that exposes the included high-flow oiled cotton filter to more incoming air, while sealing tightly against the hood to keep the box fully enclosed. It draws air through the factory air inlet ducts at the front of the car, with weather stripping around the ports to prevent movement. The 3-inch aluminum intake pipe routes all the way to the turbo inlet and includes all necessary bracketry for a secure, direct-fit installation. For enthusiasts cross-shopping this cold air intake against a k&n cold air intake, s&b cold air intake, or afe cold air intake, Mishimoto’s kit is engineered to work with the stock tune, so no additional tuning is required after installation.
