I got a very good deal on a K&N filter. I know I only have about 1500 but it was such a good deal that I bought it. I installed it yesterday, reset the mileage and drove about 80miles on a suburban driving. I was getting 24 prior, now computer showing 29. I know the computer is probably adjusting. I'd be interested to see if it will be slightly better than the original 24mpg once the computer adjust.
The response is better but I don't think its very much noticeable.
I have the 2.0 awd reserve, running on 87 octane.
Anyone else tried KN filter? The installation is very easy. I just watched youtube video of someone installing a filter on a 2013 escape, its very similar.

Please report back on the mileage. That's a huge difference.

I installed the K&N on mine in the first month, and did not get much of a baseline mileage before the swap. I have not reset the mpg display for months and it displays 27.2 average. No I don't dog it, but I don't hoof it either.

I use to have a K&N filter on on my Corvette and any change in performance and/or mileage was negligible (this was a few years back). That said, they tended to allow in more dirt than the stock filter. I could see some "grit" in the throttle body duct after the filter so I went back to stock. Keep in mind that these modern engines have very precise engine management systems that over compensate for a dirty filter and may under compensate for a filter that allows in more air. If there was a significant change in mileage you can bet Ford would be using it since it means millions to their bottom line in regards to mandated CAFE standards. Since you have the entire engineering team of Ford Motor company designing these systems (and they are systems now) for a balance between durability and performance I would continue to lean towards using stock filters

Thanks for your input.
For those are are interested on the result. Here it is.
Using 87 octane, cruise control around 70 to 75, occational acceleration when passing trucks.

Fully agree with you,OEM filters are ever so slightly more restrictive than a K&N filter regarding flow,BUT they filter WAY better than a K&N filter.
As well, you must be very careful when recharging your K&N filter with the gum oil....too much oil will coat the inside of the intake and potentially cause issues with air mass sensors.
My Mustang GTCS with bolt ons still gets OEM filter, and an oil separator ( catch can) between the PVC and throttle body... it's a good way to stop that gunk from being dumped into the throttle body for burning on the next "start" cycle.
My intake is clean as the day it was manufactured.

K&N filters will not ever increase your fuel mileage, period. Nor will it give you any increase in performance, beyond a placebo effect.

At the very best, they'll give you a little more intake sound. The oil on the filters has been documented many times over the years as causing lots of malfunctions, whether it be MAF sensors or the like.

As evidenced by the many dyno sheets for cold air intakes, the factory setups are very efficient now and don't restrict the same way they used to. K&N will not be seeing a dime of my money, I'm not trying to wreck this engine nor any of it's components, and I can buy 5 premium paper filters for the price of a K&N.

Times have changed. CAFE has forced the hand of the engine builders to actually make the most efficient intalkes possible now. Every .1-.2 mpg increase counts. The K&N era is over for me. Used to have them in everything and knew how not to over oil them. Always oil just the outside BTW

I used K&N on a Corvette I had and found fine dirt inside the duct work after the air cleaner - Stick with the stock air filter... K&N is snake oil.

I have a K & N E-9289 filter from my '14 2.0 Escape. I'm going to try it in my '17 2.3 MKC Reserve once it's broken in. The E-9289 filter has the option of removing a end plug for increased air flow over the K & N E-2993. I'd be curious to hear about any actual mileage gains with the K & N.

I use the aFe Pro Dry S. It has an open end as well. I much prefer a dry filter over the oiled-gauze.

Thanks for that info. I have a K & N, but I would prefer a dry filter as long as it has the open end. Did you notice any performance or mileage changes with this filter?

^ I wouldn't be able to positively say that it made a big difference. I also use Mountune's smooth tube to replace the ugly accordion tube. With them both, I like to think it's flowing better/smoother, and it;s only slightly louder (can barely tell).

Realize that pick several posts back showing 29.9 mpg is a pipedream because the computer is VERY optimistic, typically by at least 5+% many are 10% off on vehicles. But to see those numbers he was probably doing the botton end of 6th gear at say 60 mph on a flat road, with a tailwind.
