Roush 2012-2018 Ford Focus 2.0L Cold Air Intake Kit - 421642

Get true performance and improved throttle response from your I-4 Ford Focus with the ROUSH Cold Air Intake kit. Designed exclusively for all Ford Focus models, this open-element filter kit improves airflow over the stock, paper-element filter. As a direct replacement for the restrictive stock filter, the ROUSH intake kit features a custom ROUSH-branded air box that is topped with EPDM foam for an airtight seal to the hood. Also included is a premium high-flow air filter that is re-usable simply by washing and oiling it. ROUSH engineers were also able to utilize the factory PCM calibration, which will not void your factory engine warranty. Even better, this kit maintains the factory PCV connection on the oversized MAF tube, eliminating the need to drill or cut any of the parts. Installation is quick and easy, taking less than one hour to install with basic tools and all hardware for installation is included.
