The K&N 77-2514KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction. 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 77-2514KP 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 as well as the idle-air bypass line on some vehicle models. 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.

K&N 77-2514KP Air Intake Product Reviews

Wednesday, October 18, 2017 - Part 77-2514KP
Initially happy with the product until I drove it when it was cold out. The intake makes my truck sound like a tug boat at low RPM's and when I am at an idle. I never had my truck do this until I purchased the intake. Have had many K&N filters before this on other vehicles and have been happy with them.

Great product. Easy to install. The instructions were clear and concise. It only took 60 minutes. Performance seems to be as specified. I really like the sound it makes during acceleration. I would definitely recommend this product. Thanks K&N

Ordering was a breeze; options and drop downs were easy to navigate and the entire order took me five minutes. The product itself is awesome. I installed one in my '06 Charger R/T and experienced a definite improvement in horsepower and acceleration. Now I have one in my '04 Expedition and have enjoyed the same results. Thanks, K&N.

I put on an intake system on a 1999 F250 5.4. The instructions were easy to follow, all parts fit perfect. This truck is use to pull a 27 ft. Airstream so when we get back from Florida in Nov. I will comment on performance, but from test drives this truck runs great. What an excellent product.

I had to share this with you guys at K&N,,I have been asking a lot of my friends about this filter system and there was a lot of doubts in people's heads if this was a sure thing,,,well let me tell you, I bought the best one chrome tube system and my throttle response is a lot better. My gas mileage has increased 30 to 40 per cent more. If I kick it at 30 ,,it spins the tires. 1997 Ford f150 with a 4.6. This has to be the best unit I could have put on my truck. It took all of one hour to put on and I could have done it quicker but I like putting it back as close to the original as possible. It sounds like a deep throat with no bottom to it. I love it and will recommend this to all of my friends from now on,,really bad ass set up. At 60 years old I feel like a reborn gear head again. You know what they say,, You are only old as you feel,,21 again,,,
