AIRAID Cold Air Intake System by K&N: Increased Horsepower, Cotton Oil Filter: Compatible with 2015-2020 FORD (F150) AIR-400-293

I did a fair amount of research before purchasing this CAD.Its now been on my 19 F-150 5.0 for a month. Im 1.6 mpg better, have a more immediate throttle response and love the intake sound even with the cover installed.I do have this paired to a 3" Corsa exhaust w/resonator delete, and 85mm throttle body. No tuner!Haven't put it on a dyno and don't plan to. I can attest to better performance and mileage.Is it a massive increase...no.Does it work...yes.I would highly recommend this product. Without the other upgrades im afraid you will only see minimal gains, outside of mileage and sound.Installation was incredibly simple.I've seen other posts where people were complaining...im lost on a response to that? Assemble it first, (don't be an ass...read the instructions), have the right tools, installation in the truck should not take you more then 20 minutes. If any of those things present a problem...take it to the shop and put your wrench back in your purse.

This product was supposed to arrive on a Wednesday, but I came home Tuesday and there it was! Needless to say I changed my plans and installed it immediately on my 2017 Ford F-150 with the 5.0L. Directions were very thorough and the unit took less than an hour to install. As soon as I was done I reset my average miles per gallon and took a long drive. Now I know it's very early to tell how well it will increase fuel economy in the long run, but I went form 15.2 mpg to 17.6 mpg. Not only am I looking forward to the increased fuel economy, but it also added an improved exhaust sound and horsepower.

Opened box looked nice but upon installation nothing fit together had to modify it to make it fit right. I would of inspected this from a super cheep cold air but not from airaid was supposed to be a good quality but was not. Definitely will not purchase any new products garbage

First impressions when I opened the box, everything was shoved in there. There was some paper in between the pieces but it didn't seem to help any. The main part of the air box seemed to be out of shape on the top. Once assembled it was bent. I applied a little bit of heat and got it into slightly better shape. The cover piece was still a pain to get lined up and there is a gap (see pic). As mentioned in other reviews, most of the holes did not line up so have a drill ready to make some adjustments, nothing major but still annoying. Fit everything together before you drill and screw it together and take your time. On the good note, it sounds great. My truck does seem to drive better and responds quicker. Overall I am happy with it.

This intake is of the highest quality. Such a clean install. Also have dual side exit Magnaflow exhaust installed.Installed on a 5.0L regular cab, short bed.Truck is stupid fast, probably making 420hp. Current day lightning 🌩Highly recommend it.As far as mileage 🤣 12.4mpg

2017 F150 5.0 The Airaid intake arrived ahead of schedule, was not missing any parts, and the installation went smooth. It took 1hour and 15 minutes. Fifteen of that was trying to get the PCV hose clip off of the old breather tube. Pull up on the gray tab that is underneath and pull the fitting out. Whew! The rest was actually fun! The fit was absolutely perfect. Haven't driven it yet only to pull into the garage. I'll writ another review as soon as I do and include a photo.

Noticeable improvement in performance, response, and mileage. Fit and finish is okay. Installation took twice as long as it should have because each interface hole had to be adjusted. Not just the pictured cover hole interface with the air box, but each screw location has to be drilled larger, reamed to one side, or otherwise adjusted to get this thing together. Package was missing a flat washer and one of the small screws. The included zip ties will come in handy if your air box has a sensor mounted to it. Bottom line, if you have a few hours, don't mind tweaking fit and finish issues, and live near a hardware store in case they didn't include something, then it's a good value. The ability to reuse the dry filter is nice and not having to worry about filter oil potentially gumming up a sensor provides added peace of mind.

I have a 2018 F150. This CAI is very good quality for sure. Directions were clear as can be. I took my time and was thorough and it still only took 50 mins. I was doubtful to actually notice any power gains from it but it surprised me for sure. Definitely a little more to the truck now. A little more cab noise when you punch it now which I like but it is not overbearing. Don't know fuel mileage increase yet. Pretty happy with this purchase.
