Improves Horsepower and Torque. Completely replace the restrictive stock airbox and paper filter element on your 3.7L V6 F-150 with a K&N Series 77 High Flow Performance Cold Air Intake. Featuring a high flow filter assembly and a free-flowing polished aluminum intake tube, this Cold Air Intake will provide your F-150 with a noticeable increase in horsepower and acceleration all while still providing excellent filtration. After installation power gains of 11.91 horsepower and 10.33 ft/lb torque have been seen at the rear wheels.

Filters Out Harmful Contaminants. The supplied K&N Filter successfully filter's out harmful contaminants with it's unique layered design. K&N Air Filters are made up of layers of specially treated cotton gauze that are sandwiched between two epoxy-coated aluminum wire screens for durability. K&N uses a specially formulated grade of oil to treat the cotton gauze layers which causes a tackiness throughout the cotton's microscopic strands creating a powerful filtering media that ensures engine protection.

Washable, Reusable Filter. K&N designed their high flow air filters to be reusable. That means there is no need to buy a new filter every few thousand miles, you can just clean the filter, re-oil it, and save money with a K&N Filter Recharge Kit.

No Tune Required. Unlike other Cold Air Intakes on the market for the F-150 this K&N Series 77 CAI does not require a computer re-tune. The engineers at K&N really did their homework to improve your truck's power using the stock tune.

    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.
