Hard-Charging CAI with Proven Power Gains. A straightforward and effective upgrade to your 2012-2014 F-150’s intake system, the K&N Series 77 High Flow Performance Cold Air Intake ensures your truck’s 3.7L engine actually gets the amount of cold air it can handle. Guaranteed to grant power gains at all RPM levels, this CAI is dyno proven to be capable of raising horsepower by +11.91 and boosting torque by +10.33 ft-lbs. The silver powder-coat on the aluminum intake tube also makes it a handsome addition to the engine.

Needs No Tune Except Stock. Since it reuses the stock MAF, the K&N Series 77 High Flow Performance Cold Air Intake doesn’t require an aftermarket tune in order to work. You can utilize this component with the OE tune still in use.

High Capacity, Top Effectiveness Filter. The K&N Series 77 High Flow Performance Cold Air Intake is equipped with a cotton gauze filter whose durability is enhanced by two layers of aluminum mesh with epoxy coating. An oiled filter, this element catches a wide range of particulates while allowing maximum air inflow. It can be periodically washed and reused (first washing at 100,000 miles).

Manufactured for Reliable Action. Tough and durable materials are used in the K&N Series 77 High Flow Performance Cold Air Intake, a component that’s made in the USA. The air box is made from light but strong injection-molded polyethylene, with an EPDM foam seal along the upper edge to fit tightly against the underside of the hood, blocking out engine heat. The intake tube is rust-immune aluminum, finished with a silver powder-coat and painted with the eye-catching K&N logo.

MAF Housing for Factory MAF. The K&N Series 77 High Flow Performance Cold Air Intake has a MAF housing that fits the factory MAF exactly. There are also fittings for mounting the crankcase vent hose and EVAP vent hose.

Bolt-On Part with Fast Fitment. Hand tools like wrenches, screwdrivers, and a ratchet set are all you need to successfully install the K&N Series 77 High Flow Performance Cold Air Intake. The component is made for bolt-on application to the current mounting points, and comes with all needed hardware.

Warranted for a Million Miles. The warranty of the K&N Series 77 High Flow Performance Cold Air Intake is one of the longest possible short of a lifetime, with 1 million miles of coverage.

Ready for Use in All 50 States. CARB certified, the K&N Series 77 High Flow Performance Cold Air Intake can be driven anywhere in the United States – it is 50-state street legal. The CARB Executive Order (EO) Number is #D-269-48. The component can be purchased, used, and driven on streets, roads, and highways in California or other locations that use CARB regulations, as well as the rest of America.

Application. This K&N Series 77 High Flow Performance Cold Air Intake is specifically design to fit the 2012-2014 F-150s powered by the 3.7L V6 engine. Technical Note. The K&N Cold Air Intake is not designed for F-150s equipped with a body lift.

    2012 3.7 v6 supercab

    Installed the kandn air filter just 35-40 minutes as advertised definitely notice the low end improvement as the power band on the 3.7 was noted for hitting around 4000rpms this seems to have moved that down to hit stronger from 2500 to 3500 should help when I hookup to the boat Pleased with the performance so far

    Better Performance

    The intake was very easy to install, less than one hour. No real change in fuel mileage. The truck runs better and has more power. It seems to have a flat spot about 1800 rpm. Can get a bit noisy when you get into it, otherwise sounds not much different from stock.

    Great Cold Air Kit!

    Very nice kit. Easy to install. Just follow the directions and you will be good to go! Added power in the middle to upper RPM range. Really growls when you put your foot into it. What's not to like?

    lots of noise

    So this is the 2nd time Ive used this type of product, this brand is quite loud altho not in a bad way but I don't know what it sounds like outside of the truck either, after getting up to speed it quiets down and it sounds like its doing something, I think I'm noticing more throttle response from stop but not sure if this means more performance without any testing, but it does feel like its breathing easier so I'm pleased with what I have.

    Easy Install

    Everything fit great and my truck sounds awesome with the KandN Intake and Flowmaster exhaust. Gas mileage actually went down because I can't stay out of it now.

    Good bang for your buck

    So bought this for my 3.7L V6, less than an hour install start to finish, and love it. I can definitely hear it. Sounds amazing. Better fuel economy. Truck run better. Only problem, truck still can't do a burnout, gotta get more upgrades... Luckily I got my 13 5.0 for burnouts.
