Air Filter

[rollinstone]

Opinions seem to be all over the place, but from what I can glean there's not a lot of love for K&N Air Filters. General consensus is go with OEM. OEM (Motorcraft) was engineered for the engine and should stay with the engine.

That said, some proponents of K&Ns said they're great if your racing or doing other performance kinda driving, but for daily drivers go with stock filters.

Leery of dealer prices. Some after market places say their filters are just as good as OEM, but who knows?

Any recommendations? TIA

I had a K&N in my 2014. I went to clean it the first time after about 30K miles. I wasn't impressed with the end result. Threw it out and picked up a Motorcraft for less than 20 bucks at Advance Auto. There is literally no noticeable difference, if anything I think the stock one is quieter.

in my 2017 xlt I use the cheapest brand name air filter and change it every 5K mi when I change the oil and filter. this time it's a Fram extra guard $10.60. I've used OEM, STP, Fram in the past.

K&N makes more power by flowing more air (and dirt) which leans out the pre-programmed fuel table trims when you switch to Open Loop ECU operation. All other times, a K&N is just flowing more air (and dirt) while the engine is producing 75 hp to drive down the street (I made up the 75 hp number).

So if you drive in Open Loop a lot, a K&N might help you get you where you’re going faster.

K&N and other oiled filters= more money and maintenance. The filter cleaner and oil has to be done and if you over do the oil by a little bit, you end up cleaning your MAF sensor and throttle body. Do to little oil and you let dust in.

Cheap filters=less money and maintenance. just put in

and like hound said,

There is literally no noticeable difference

and unless you travel around everywhere WFO there is no difference.

I’ve always bought the STP or Motorcraft Filters from autozone whichever is in stock. They carry both near me. Never had an issue with either. I change them more often than most because when I go down to the cabin there are a lot of dirt roads....I generally get 10-15k miles or so.

I have always just used whatever name brand filter was on sale at the time (eBay, Amazon, RockAuto, Advance Auto [were cheap w/ rebate]). Motorcraft, Purolator, AC Delco, etc.

This. Just get a decent brand filter and go. Motorcraft filters are fairly cheap. You can buy about 15 of them for what a K&N intake costs. If you aren't doing an intake their filter is not going to be any sort of benefit anyway.

K&N only benefits the sellers with all their hype ........worthless. Also all Ford trucks already have a cold air intake ......look a little deeper.

Wix filters for me

At least the OP didn’t ask what is the best oil filter to use...........

 

[1oldtimer]

I use motor craft or wix filters only. And wix is my first choice.

 

[07navi]

motortcraft

I run WIX filters, but I also buy more WIX filters than anybody in the state so I get a hell of a deal. The joys of heavy equipment.

Had bad luck with every K&N filter I've ever used - car, truck or motorcycle; not worth the money and hassle IMHO. I change my air filter every April - that's about 10-12K miles, max. I use whatever is on sale; generally find one on ebay for $10-$12 - in fact, I just ordered this year's replacement. I don't drive too many dusty roads and, once the salt/sand dust on the roads gets washed away, things are pretty clean around here.

I used Airaid drop in filter for my 2008 Expy, with Ford Motorcraft oil and filter

AEM Drop In! Works really well it’s not an oiled filter!

Almost every vehicle and engine I own has a K&N air filter. If K&N makes an OEM replacement, then that is what it gets. Paper filters are trash.

Such a convincing argument.
