Review & Installation Video

Review & Install Video

What's going on, guys? I'm Alex from and this is my quick review and install of the K&N Drop-In Air Filter fitting the 2009 through 2016 F-150. So in this video, I'm gonna talk about the construction and materials used in this filter, who this might appeal to, as well as touching on the installation a little bit later in the video. But right off the bat, I'm gonna be giving this a very easy one out of three wrenches on the difficulty meter. We should have this on your truck in about 30 minutes to an hour tops. So this is gonna appeal to the truck owner that's looking to replace their factory paper filter with something that's gonna be that much more breathable, longer lasting, as well as even in some instances creating better flow, horsepower and even some improved fuel consumption. So in terms of the construction of this filter here, guys, we're gonna see that K&N is gonna be using their unique, layered cotton design here that's gonna be then sandwiched between epoxy-coated screens which are going to ensure durability as well as longevity. So one of the great things about K&N's filters is that they're gonna feature a specialty-formulated grade of oil that's gonna be applied to the cotton gauze here. Now, the purpose is for that to filter out any kind of contaminants from going into your engine and being harmful. So take a look at the pricing here, guys. We're gonna see that this drop-in filter is gonna fall in line right around the $50 price range, which is typically what you're gonna be spending for a replacement filter. In my opinion, this is a huge bang for the buck as you're gonna have a K&N quality product here that's gonna filter out any type of contaminants from your motor as well as having a washable and reusable filter that's backed by K&N's million mile warranty. All right, guys, so taking a quick look at the installation here, even if we could call it that. You're gonna be looking at a very easy one out of three wrenches on the difficulty meter and about 15 to 30 minutes to swap your factory unit with this replacement. Now again, I can't stress it enough that just based on the installation alone, this is a huge selling point for me as you're essentially going to need to open up your factory air box and then replace it with K&N's unit and you're good to go. All right, guys, so just to wrap things up here, I really like this option from K&N not only based on the fact that you're gonna have a filter that's gonna be backed by a million mile warranty, but for the fact that you're gonna be protecting your engine from any type of harmful contaminants that could get in. So that's my review and breakdown of the K&N drop-in replacement filter, putting the 2009 through 2016 F-150 available right here at

Filters out harmful contaminants. The K&N Drop-in Air Filter filter's out harmful contaminants with it's unique layered design.

    Simple, Cost Effective Upgrade

    Like others, I run KandN on all my vehicles. First found them through a motorcycle upgrade 17 years ago. On cars, and now the truck, the filter provides an instant performance boost, I've even noticed that the vehicles sound different with a KandN filter. Several years ago, KandN started selling a cleaning and recharge kit that allows the re-oil to be sprayed on - that system made it even easier to maintain the filter, eliminating the worry about over-oiling them. You gotta replace the stock filter occasionally, it makes sense to spend a bit more for a better filter that can be cleaned and reused over and over. If you are into your vehicle for the long run, this is the most cost effective choice.

    Great Quality and easy install sent out the filter quickly and it was in great shape when it showed up. Already oiled, it was a 30 second install and it was easy as that. Make sure you wipe off your MAF sensor about a month after install because excess oil blows onto it when its new. Will order again for my Wifes car too.

    Simple K N upgrade

    I purchased the KandN drop in filter because it was a simple way to reduce my long term expense on filters and increase gas mileage. I already have a KandN filter in my 2008 Mustang so it was a quick decision to upgrade my 2016 F-150. The installation was as easy as changing the air filter.

    It is a simple upgrade. All the stats point to improved mileage and performance. I think it is a good investment for long a long term air filter as long as you take care of it and clean it. Any performance gains, even if minor, are a bonus in my opinion.

    I purchased this drop in filter with some expectation, after reading about it and after having it installed for approx. 10K miles now, I am not as impressed as I had hoped to be.. I do see some difference in the acceleration, but I'm not seeing any improvement in gpm or horsepower as advertised.. I'll leave it in for a while and give it a little more time..

    Was expecting more

    Based on all the other reviews about better fuel economy and increased responsiveness, I guess I was looking for more. Truth is, the responsiveness is there but I certainly don't get better fuel economy with this.

    Improved Fuel Economy and Throttle Response

    Overall I am very pleased with this drop in filter. I drive a 2016 5.0 Super Crew 4x4. I purchased this KandN with the hopes of improved mpg's and performance. It delivered. I went from getting 17.3 mpg average to 18.6 mpg. The throttle response in proved some as well. American Muscle shipped quickly and offered the best price online.

    KN Does the trick again

    I love KN panel filters. They always make the vehicle breathe better especially out of the 5.0. I have notice better MPG and letter acceleration. Keep in mind that you need to clean your MAF after the first month of use as oil from the filter gets on the MAF.
