      Description

      CAI with Good Sound, Performance. Energizing your 2009-2010 F-150 with up another 15 horsepower, the K&N Series 77 High Flow Performance Cold Air Intake gets your truck’s 4.6L 3V engine breathing easier with its big inflow of cold, oxygen-rich air. Made to not only boost throttle response but to give your pickup’s engine a stronger, meaner sound, too, this tough CAI won’t need to be replaced for at least a million miles. You won’t need to service it until after the first 100,000 miles, though some types of driving may clog it up with dirt and grime, meaning you need to clean it sooner.

      No Tune Needed. A plug-and-play component, the K&N Series 77 High Flow CAI can be fitted to your F-150’s 4.6L engine and start offering power gains immediately. The cold air intake will function strongly and problem-free with the stock tune still in place. However, upgrading to a specialized tune will squeeze a few more horsepower and ft-lbs of torque out of the setup.

      Many Useful Traits. With a built-in heat shield, mandrel bent aluminum tubing, and a huge conical air filter, the K&N Series High Flow Cold Air Intake is built to deliver lots of air reliably to your truck’s motor. The filter itself is washable and reusable, so you can remove it, clean it, oil it, and return it to the CAI during the component’s life. The intake develops a strong air charge for higher power and acceleration.

      Built for Long, Strong Service. Premium materials are used in the K&N Series High Flow Performance CAI, including rust-proof polished aluminum for the intake tube. That tube looks great in your engine, besides functioning well. The included clamps consist of stainless steel for long-term durability. The round filter is made from red cotton gauze, with an oversized design to allow plenty of airflow. The gauze is oiled and sandwiched between two aluminum screens to make it stronger.

      Includes a MAF Housing. The K&N Series 77 Performance Cold Air Intake includes the necessary space to mount the factory mass air flow sensor of your 2009-2010 F-150. There are also attachment points for the crankcase vent hose and the air temperature sensor.

      Fast Bolt-On Install. The K&N Series 77 High Flow Performance Cold Air Intake bolts on directly in place of the stock air box. Installation uses hand tools and a bolt-on approach, using the included hardware provided with the kit. Total time for the swap is 1.5 hours (90 minutes) or less.

      Million-Mile Warranty. This long-lasting K&N Series 77 High Flow Performance Cold Air Intake is covered by the company’s standard 1 million mile warranty.

      Complies with CARB, 50-State Legal. Operating under Carb EO Number #D-269-48, this particular model of the K&N Series 77 Cold Air Air Intake is 50-state legal. It can be used in the state of California and in other jurisdictions where CARB regulations apply. Note that not all variants of Series 77 intakes are CARB compliant, though this one is.

      Application. This K&N Series 77 High Flow Performance Cold Air Intake is specifically design to fit the 2009-2010 F-150s powered by the 4.6L 3V (3-Valve) engine. 4.6L Application Note. To determine what version of the 4.6L is in your truck, you would need to refer to your VIN number. If the 8th digit in the VIN # is "W" it is the 4.6L 2V. If the 8th digit in the VIN # is "8" it is the 4.6L 3V.

      Technical Note. The K&N Cold Air Intake is not designed for vehicles equipped with a Body Lift.

        Cold Air Intake

        Great product, makes a great mean sound, and gives a great throttle response and adds some real torque, most of all hope to see some gas mileage improvement.

        Cold Air Intake

        Make sure that the adapter hose from the box to the tube is against the MAF sensor, or you will hit the hood when closed. Also the trim strips provided (Both upper and lower) for the cold air box could be 2" longer for better sealing. Sounds good at idle, but will test the fuel mileage to see if I gained anything.

        Amazing sound

        Easy to install and the sound from this alone without a muffler or catback upgrade is unbelievable a noticeable increase in power as well

        Worth every penny

        At first when I bought this, I was a bit skeptical, then after installing it, I could tell the difference in terms of throttle response, and sound. If you are looking for Sound, performance, and looks, I would highly suggest purchasing this cold air intake .

      5 Top Rated Questions

      hello im looking into buying something like this. My two questions are why does it say this will not fit if I have a body lift? My other question is what is the difference from this and the black out series other than the color and price. Just trying to figure out which one I should buy thank you.

      • The K&N Series 77 High Flow Performance Cold Air Intake attaches both to the engine, which is mounted to the frame through the K member, and it attaches to to the body. When installing a body lift, the distance between the mounting points change, and this intake is not flexible enough to accommodate for this. The K&N Backhawk would have several minor differences in design, but the primary differences are the black powdercoat, and black filter.

      What is the performance difference in the 57 and the 77?

      • The performance difference as per K&N's website is the 77 series will add an estimated HP gain of 15.07HP @ 4650RPM and the 57 series will give you an estimated HP gain of 16.14HP @ 4650RPM. So they are very close in performance.
