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.

Kit arrived on time, instructions were good, everything fit with no issues. I can feel the improved horsepower in my 2012 F-250.

Clean simple install. Haven't had it on long enough to document differences fully. A little louder on hard acceleration from stock. Better pedal and response off stop.

Fast delivery, all the parts were there and were the right ones. Truck seems to perform better but have not got it out on the highway yet.

Was delivered on time. I'm not a mechanic by any means but do know my way around. The install took me 40 minutes from start until start up. I did read the directions before and during the installation. I read a few reviews before ordering that complain about the noise but the only time I get any real noise is when I kick into it and then it just reminds me of the old days hearing that 4 barrel opening up. Milage I couldn't tell you because I didn't track it before the installation, power yes there is a noticeable gain. I have been running K&N on my vehicles for years and I am glad to have this cold air intake on my 2011 F250 I'm not trying to build a race truck but between a performance exhaust and the K&N I have the extra edge to get around the dummies on the road.

Super-easy installation on my 2015 F250. All parts appear to be of quality. This kit has provided much improved throttle response. My only ongoing concern is that the crank case vent hose might be a bit shy on length...will continue to monitor whether I need to replace with a longer section of hose.
