The K&N 77-2582KTK high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Ford F250 and F350 Super Duty truck 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 77-2582KTK air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs onto the lower air box. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive textured black powder-coated 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, ratchet set 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.

  Easy to find needed item. Good description and price. Prompt shipment.
Victor Stevens Petersburg, Michigan
  The claim for more horsepower stands strong . My intention for the purchase was to gain a few more MPG. My F250 has been on both city and highway quite a bit and I have yet to see any positive effects on my MPG. A little disappointed . Overall rating stays strong though!

  I installed the cold air intake on my 2015 f250 super duty with 6.2 ENG. The truck was very slow to respond from a stop. I installed the cold air intake and it was as different as day and night and I have gain about 1.5 mpg so for my money this was a great buy. I have used K&N filters in several of my auto's THANKS K&N

  I love it. It has better throttle response and more mid range power. It has a nice sound at full throttle that just sounds mean. Fuel economy went up also. Due to larger tires, I can't tell you the exact amount but I would say an average of 1 mpg better. Of course I drive it a little harder now also.

  Just installed this a week ago in my 2014 F250 6.2. The jury is still out. I have not felt or seen a significant change in power or gas mileage. Though it gives the truck a deeper throttle sound when I give it gas.
