K&N Cold Air Intake Kit: High Performance, Increase Horsepower: Compatible With 2017-2021 Ford/Lincoln (Expedition, F150, F150 Raptor, Navigator) 3.5L V6,63-2599

I added a K&N cold air intake to a car of mine (a Mazda 3 GT-S) a few years back after driving that car for a few years. Right away I noticed the increased 'pep' in the car, the improved gas mileage and the 'growl' of the engine, especially when accelerating. When I purchased a new Ford F-150 Lariat, I checked to see whether or not I could expect similar results by adding a K&N CAI. I only had the truck about 2 weeks when I added this, so the OEM air filter looked brand new when I took it out (anybody need one?) but as soon as I installed it, there was that growl and I actually did see - assuming the in-dash info screen is correct - an uplift in MPG of about 15% once I'd driven for a while. Installation is pretty straightforward and I'm certainly not an auto mechanic. Just follow the instructions. Moving the inlet air temperature sensor from the original setup into this is a bit of a pain (be careful!) but once that's done and everything is moved into position and tightened up you're good to go. All in, installation took about 1/2 hour. At the time of purchase, there was a rebate which made this an even sweeter deal. Update August 22, 2019: My truck started showing the Check Engine Light ("CEL") so I used an OBD2 reader to find out why. The code that was being generated was P04DB which an online search showed was likely related to adding the intake. I called K&N customer service, explained what was going on to "Joel", gave him the P04DB code and he knew right away what to do. He sent (express shipping) a small metal tube which you can see in the center of the second image I added to this review. In the image it's sticking out by about 5/8" because it's too long. Another chat with Joel and he advised to cut the tube down to the appropriate length which I did with a hacksaw and then used fine sandpaper to make the edge smooth. Once that was done and the metal tube was installed, I cleared the code and the CEL went away and it hasn't come back. Somewhat disappointing that this had to be done, but I have to give kudos to K&N support for knowing right away what the resolution would be and express shipping the needed part so I could install it before leaving for a long driving trip. Still a 5-star part and overall experience to me. Hopefully this will help someone else with a similar issue. 2019 Ford F150 Lariat, 3.5L V6 w/ EcoBoost

The product was easy to install and works great. Installed on a 2018 Ford F-150.

Easy to install, came with clear, easy to follow instructions and included a pigtail wiring extension for the Intake Air Temp sensor. Everything fit like a glove, the clamps are an upgrade over the stock ones (go from 7mm stock ones to 8mm K&N ones) Since driving hundreds of miles with the intake, I noticed a little better throttle response, I like the sound of the engine with this intake, and my overall MPG went slightly up (maybe 1mpg) Recently I ordered a SCT tuner with 3 of the 5 star tuning tunes on it, waiting for it to arrive in the mail and that should really bring the power out of this 3.5L Ecoboost, but that’s for another review.

Facile d'installation et donne un beau son!!

I installed this on both of my F150's. One is a 2011 and the other is a 2018. They are both equipped with the 3.5 ecoboost engine. This air filter increases the air intake and has improved the gas mileage by 2 miles per gallon. It was very easy to install.
