Love K&N products and this cold air intake is great! The turbo noise is opened up and sounds amazing. I’ve noticed I get about 1 MPG better with it installed. I have not tested any hp gains but i assume they’d be minimal. Over great product!

Install was simple. In fact my teenager who is 16 and knows little to nothing about auto mechanics installed this with just some assistance from me just taking a few tips a from "youtube" video of how to install it.First noticeable difference driving is my truck has better throttle response.As far as sound, I hear a little bit more growl from the air box. Nothing crazy or nothing that would annoy me while casually going down the road. In fact as far as sound goes under normal driving can't really tell anything.

Price and quality can’t be beat from any other brand that’s made in the USA,, And if you ever need a replacement filter they are easy to source from anywhere that supplies K&N Parts and filters, A Lot of the other USA made after market air filter kits come with some weird,,possibly imported,,CHEAP,,filter,,that probably can’t be replaced once they need to be replaced without buying a whole new kit ,,or trying to contact the manufacturer and getting the run A Round about a replacement element and price

Fairly simple to install, this took about 45 minutes all said and done. I put this on my 2023 F150 Tremor and have had no issues so far. Comes with all the necessary parts and even some extra things that may need to be used on earlier model Eco-boosts. My mpg increased noticeably on the highway and the truck seems to be a little more responsive, more intake noise plus hearing the blow off valve when I let off the gas. I like it!

Installation on my 2024 3.5L EcoBoost F150 was easier than expected. So far no issues, engine sounds great, turbos seem more responsive. Hopefully performance is enhanced, time will tell.

After I correctly installed the kit, it ran fine for about 30 minutes. Then the check engine light came on. The kit threw off my crankshaft sensor. Would not recommend buying. Went back to OEM and returned the item. Not worth the money

7-30-2023: Even with the turbo restrictor tube and researching everything I could find, this intake still causes my truck to throw the P04DB code. In my initial review I mentioned a gain in fuel mileage. This lasted a week tops as the truck readjusted itself back to normal. I just came back from a 1200 mile road trip today and averaged 16.5 on the DIC, running with the cruise set on 75 as much as I could...engine light and all. I got the same with factory. I got home, pulled it and went back to stock. I'm to the point I don't think will work with my truck unless it's tuned and since I'm still under warranty for about three more years, no tune in sight for me.3-14-2023: It throws the P04DB code on my truck, not all the time but sometimes when I do more 'spirited' driving. Contact K&N customer support for the free turbo tube restrictor to help with the code. Even with the part it will still throw it on occasion. Buy a cheap code reader/code clearer to keep in your glove box.Typically I don't expect too much from a new intake but my acceleration is smoother, more responsive and if you can keep your foot out of it, my last two fill up's have netted me ~ +2-2.5 mpg average MPG. My last fill up, average mileage was in the low-to-mid 15's which doesn't sound like much until you realize I was in the 13's before that, sometimes high 12's. I do a lot of in-town and stop-and-go driving. Highway is the same but I'm using far less skinny pedal around town. Passing was not difficult before but you really notice the quicker acceleration when you get into it to get around those 18 wheelers.It fits. A bit like a jigsaw puzzle where the pieces need a little forcing to fit but it works and looks good when done. Not much turbo whistle which IMO is nice. Airflow sensor is moved closer to the air box requiring the extension. Not sure why they did that. Had to use a few zip ties to keep the extension cable from jumping around. Should let the 3.5 H.O. breathe a little better. Seems to accelerate smoother as well.

This was easy to install. I took my time and it took like 20 minutes. After going from the factory 2 ply tire to an 8 ply, my 21 f150 ecoboost no longer pushed me back in the seat when flooring the gas. That is back plus a little more. The engine now has a little growl to it and the exhaust sounds great. I did not expect these added benefits but am pleasantly surprised. Well worth the money in my opinion.
