This Injen Power-Flow 3-1/2" cold air intake for 2015, 2016, 2017, and 2018 model Ford F-150 2.7L or 3.5L Ecoboost V6 and 2017-2018 Ford Raptor 3.5L Ecoboost features their patented MR Technology and is designed as a direct replacement for the 2.7L and 3.5L Ecoboost vehicles' restrictive, stock intake system. Injen's cold air intake is the best way to free-up hidden power from within the twin-turbocharged Ecoboost engine. The patented MR Technology Process is leading the way in the cold air intake market. With so many vehicles being built today that utilize the latest technology available, making safe, reliable power gains is a concern. These newer vehicles have very sensitive factory air/fuel ratios, MR Technology will not only allow the intake to be tuned within that factory ratio, but will optimize horsepower and torque gains across the board.
