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.

August 5, 2015 - Part 77-2582KTK
This product works very well and as promised. I have noticed a definite increase in horsepower and expect to get an increase in gas mileage from my 6.2L V-8. I used the K&N air intake system in my previous truck, a 6.8L V-10 and experienced an increase in horsepower and a 5 increase in gas mileage. A great product and it took less than an hour to install.

Easy to install, sounds good, I have a lot more low end, and great power around 3000 rpm.

Everything fit except the pcv hose does not hook on to the K&N tube from filter to intake. Existing nozzle had a slightly larger shoulder for pcv tube to snap over. Had to rig up a replacement hose. Other than that everything fit perfect.

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!
