The K&N 77-2585KS Air Intake fits some Ford F150 models. See vehicle applications link for details.
The K&N 77-2585KS high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ford F150 models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-2585KS air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs onto the lower airbox. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive silver powder-coat finish that's made to last and it accommodates the factory mass air sensor, EVAP vent line and crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, pliers and several wrenches. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

K&N 77-2585KS Air Intake Product Reviews

Tuesday, November 6, 2018 - Part 77-2585KS
Installed on a Ford F-150, 2013, XLT, Super Crew, 3.7L. A quick, easy way to improve performance. Install is a breeze with detailed instructions, including many pictures, which IMO is ideal. Immediately improved power and mileage noticeably. The sound change is just icing on the cake. Makes my truck growl and that growl is backed up by power. The 77-2585KS Performance Air Intake System is worth every penny of the cost. I am not a gearhead so I cannot discuss esoteric devices and tricks, but I know what I feel and see, and what I feel and see is good enough for me, and probably you also. K&N lives up to its reputation here. I have used K&N products for many, many years (even on my 1974 H1 Kawasaki) and they have earned their rep for top quality products. I highly recommend the 77-2585KS Performance Air Intake System.

Amazing fit and finish. In addition to the intake, I installed a 3 CAT back exhaust and Flow Master system. I couldn't be more happy with the overall performance.
