Specs & Features CARB Status: CARB EO #D-761-2 (2015, 2016, 2017) Computer Tuning Required: No JLT's 2015-2021 EcoBoost Cold Air Intake is better than ever. Fully computer designed to optimize space and for best fit and finish. Large 5" filter inlet with radius end for tons of smooth air flow.Turbo end is 2.25" to meet up with the factory turbo, but then it steps up to 4" with another "barb" in the tube. So when you add a bigger turbo all you have to do is cut the end of the tube and add a larger coupler to fit up to a 4" Turbo inlet!! HEAT SHIELDFully Roto molded heat shield and included fresh air duct to the grille designed to keep inlet air temps as cool as possible. AIR FILTERWe use only the best air filters made by S&B to our specifications. We love S&B's tapered flange design and Powerstack filtered ends. With a huge 5” opening on the tube we needed a huge filter. The result is a monster 5x7” filter with built bellmouth to smooth and straighten airflow.
