The K&N 77-2550KP 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 77-2550KP air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory mass air sensor, air temperature sensor 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 some 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.

Customer Feedback

I put a K&N in my 2004 Ford F150 FX4 right after I bought it. Nothing but great satisfaction with it. Averaged 22-24 mpg on the road. Not too shabby for a 4x4 with a 5.4ltr V8. The end of March, this year, I downsized to a 2016 Subaru Forester. Ordered a K&N the same day. Arrived in perfect condition and the car runs great. Have already noticed a pick up in power and better mpg than the factory states. I have nothing but great things to say about your product. Keep up the great work.

I didnt think it would make that much of a difference. My 02 Ford F150 4.6 has been having issues with power and it was dogging out on me. I went for a drive after i installed it and WOW It sounds so mean and the power is unbelievable. I wasnt expecting that much of an increase. Ill have to drive it more to see if the problems went away. I struggle up the same hill every day on the way home from work when i just took it out i accelerated faster up the hill than i did before on flat ground i fell in love with my truck all over again. Thank you K&N you guys are amazing I am forever grateful i am going to tell everyone i know about your product.
