Description: MAXIMUM PERFORMANCE Our cold air intake for the 2011-2014 Ford F-150 3.5L Ecoboost was engineered to minimize air restriction and flows 28.33% better than stock. This kit comes with a fully enclosed airbox that protects the filter from dirt and keeps out engine heat. The Sound of Performance. The huge air filter and tube produce a more aggressive sound than stock. Click the play button to listen from outside and inside the cab. FIRST OF ITS KIND. Unique silicone cuff allows tube to pass through the air box. This isolates vibration and engine movement while keeping out unwanted engine heat. S&B is the first company to implement this design proficiently. BIGGER & BETTER THAN OE. The stock inlet is small and restrictive. We custom molded a rubber inlet with a generous radius to reduce the restriction of air as it enters the intake box. A 48% improvement over stock. CARRY LESS INVENTORY. ONE KIT FITS ALL MODEL YEARS. Our competitors have multiple part numbers to cover 2011-14 model years. The S&B intake comes with both MAF and Pressure Sensor mounting hardware, so you can fit all the model years with only one intake part number.
