Description
The Mishimoto MMAI-RS-16WBK is a full performance air intake system engineered specifically for the 2016-2018 Ford Focus RS, replacing every core component of the OEM intake tract including the airbox and intake pipe. Finished in Wrinkle Black, this cold air intake was developed through extensive dyno runs and road testing to deliver a repeatable, tune-safe performance gain on the stock ECU calibration.
This air intake system pairs a 3-inch aluminum intake pipe with a CNC-machined MAP section that routes cleanly to the turbo, along with a redesigned airbox that improves pressure drop by exposing the high-flow oiled cotton filter to more incoming air while sealing tightly against the hood. Like other cold air intake filter setups, it relies on the factory air inlet ducts at the front of the car to feed cool, dense air into the engine, and weather stripping around the ports helps keep the airbox fully enclosed against heat soak. Whether you’re comparing this to a k&n cold air intake, an s&b cold air intake, or an afe cold air intake, the Mishimoto kit is built around a no-cut, no-modification, direct bolt-in installation for the Focus RS platform.
