K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Towing: Compatiable with 2007-2014 FORD/LINCOLN: Expedition, F150, F150 SVT Raptor, Navigator, 57-2575

Product was easy to install, it arrived extremely late. This product did not improve my gas mileage even after I had my system cleared and tuned by certified mechanic. This product did increase my air intake which did increase my horsepower and speed. It sounds cool as well. I’m generally happy with product however in order to be honest I have not seen an improvement in gas mileage in the last 3000 miles on the highway or in town. I have noticed a more efficient working engine. As per the computer.

I installed this on my 2010 Navigator in about an hour. The instructions are pretty decent, but I would always recommend watching the install video on K&N's site.As far as performance, it definitely seems to have added a bit more power, and mileage is either the same or slightly better (around 18.5 mpg @ 75 mph). I like how K&N actually has a money back guarantee if there are no power gains. The other added bonus is the sound under heavy acceleration. There is almost no sound difference under light driving conditions, which is perfect for the Navigator. There also isn't that highway droning sound you tend to get with a performance muffler.The only negative is that the tube is plastic instead of metal. It's not a huge deal, but I've had other K&N cold air intakes that were metal. Also, the engine cover does not bolt back over this which would have been nice.One thing I was never clear on is the difference between this and the 63-2575. I asked K&N's chat and they said they were the same, just this one is California compliant. They really were no help. The dyno results that come with this are from the 63, so it could just be that the 57 is the newest version.

K&N air filters are supposedly the one of the best brands out there and damn it makes the engine block look just that much sexier. i have been running it for a few months now and i checked to make sure there wasn't any dust particles inside the tube and it was clean as a whistle. installation was easy instructions were helpful took about a half hour. i recommend cleaning out the throttle body while you're there. i have gotten about .4 MPG increase. i didn't really count the first couple of weeks as i was testing it out so don't expect to much out of that. I haven't hooked up my truck to any fancy computer but if there was a horsepower/Torque increase it's hardly noticeable. i really just wanted to get rid of that ugly OEM intake assemble and have a reusable air filter that i can clean whenever without spending money on a decent disposable air filter. Th one thing i was surprised with was the sound it make. if you hit the gas just right it'll give a nice loud low roar. that was even before i put in an MBRP exhaust. I would recommend if you're ditching or replacing the OEM filter assembly but the price is pretty high for what you're getting. don't expect a dramatic change to you're truck.

Ordered this CAI after tons of looking and reading reviews. I installed it on my 2010 F-150 Platinum 4x4 Screw. Installation was a breeze, I believe it took longer to remove the parts from box and packaging than the actuall installation. One thing to watch for is putting your mass air flow sensor in backwards. (I learned this the hard way because truck would not run). As far as performance I can tell a noticeable difference when passing cars on the highway and getting onto the interstate. I also have got 2 mpg better since installation which is great!The best part of the CAI is that it sound MEAN!!!! My 5.4 will growl and scare off the Hemi's!

WORKS GREAT

after researching for hours and reading mixed reviews i decided to wing it and buy this. I have a 2010 f150 crew cab with the v8 5.4 3v motor.I have the truck running a custom tune. I installed the intake in about 1.5-2 hours taking my time. If you are wondering if you will be able to hear the intake the answer is yes. No you wont hear it when you start the truck and idle or even gas it but when you get on the highway and need to gas the truck the intake makes the truck sound like it has a mild exhaust. I can hear a nice roar and you can definitely hear the intake breathing in air on the highway with no issue, especially if you floor it after the exit ramp. Watching videos on youtube trying to obtain how this will sound will not work. JUST BUY IT!!!! you wont regret it.I have not had this on long enough to really determine if i am getting better mpg or not but at the end of the day its only a bench mark and really not even worth discussion. you will NOT notice 4+ mpg or even +2 mpg on this, its just simply a intake system which allows better air flow vs stock allowing the engine to breath more. When empty , fill up the tank. 🤙

Looks and sounds a ton better than the monstrosity the previous owner of my truck created. The actual assembly took longer than installation, just requires patience and putting the airflow censor on correctly. I would recommend.

High price for cheap Chinese quality. Screws easily stripped. Fit is about 1/4 inch off. If I wanted all this problem, I would have just bought me a cheap one from Ebay.
