The K&N 77-2588KTK 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 77-2588KTK air intake comes with a K&N high-flow air filter and replaces the entire factory air box assembly. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The air 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.

K&N 77-2588KTK Air Intake Product Reviews

Saturday, September 22, 2018 - Part 77-2588KTK
Unit arrived well packaged to protect against damage during shipping. Showed up on the date promised. Install went very well and took less than an hour. Felt an immediate improvement in the responsiveness of my truck. This is not my first K&N product, just my first K&N Intake System. (Moved out of California so now I can make a mod like this and realize the full potential of the truck. In short, K&N website was easy to navigate, intake system is as described, install was easy. I'd recommend this product and I will continue to buy K&N products.

Took me an hour to install, the sound is great just a little bit louder than expected. Getting about 1.5-2 MPG increase. Noticed the lower RPM. Haven’t towed with it installed yet but I am slightly concerned on the higher decibel level in the cabin while the engine is operating at a higher RPM.

Excellent product, perfect fit, no altering, installed in about an hour. Engine sound at idle did not change, added very nice growl under exceleration.
