Compelling argument for OEM Air Filter

[got3fords]

This guy has a lot of interesting and entertaining vids. This one about OEM vs aftermarket or K&N is very interesting. Full disclosure, I run a K&N which is currently on the wood clothes rack drying.

F*** scotty kilmer lmao. Guys a tool.

I run an AFE ProS dry filter.

Scotty's a little tough to take at times but he does have some pretty good videos. I always run the stock filter when they're available and Wix when I can't find the stock ones.

A decade or two of seeing wasted turbos come in for repair has me a little biased against the K & N filters. In a perfect world and following instructions to the tee along with monitoring your intake restriction the K & N will perform as advertised. Any deviation from that results in reduced turbo life. Plugged to soon = thrust bearing failures. Too much oil results in crud build up on compressor wheel, intercooler and throttle body and so forth. As a protocol we always asked what type of air filter the customer was using when a failed turbo came in. Also got to see the filters on the vehicles in our own shop. Again if you are meticulous with how your using the K & N filters you should be fine. Our shop quit putting them on and recommend dry filters. If the customer insisted then there was a waiver comment on the repair order. Just speaking from experience

Agreed, I was ready to dismiss him after I watched one, but some things he says actually makes sense. The one where he blamed over-oiling of a K&N and it's consequences gained him some cred.

Good stuff, which makes me wonder 1. why does the Ford Performance tune include the K&N and 2. are they meticulously maintained by the dealership as required to avoid said issues?

Tbh, any mechanic will say the same thing though.

High performance filters will always be harmful for an engine in the long one. Don't need a guy with a horsed voice shouting that.

Yeah some of his videos are almost unwatchable because of the way he goes off on things. But I do think he's got better over that past couple years because now his videos seem shorter and more to the point without all the drama. He does have over 5.5 million subscribers so he must be doing something right. lol

Amazingly our local Ford dealer will, if you ask nicely, put together a "service kit" for you which has a Motorcraft air filter, oil filter, and diesel fuel filter, for actually slightly less than a similar kit from one of our leading aftermarket suppliers - which to be fair is probably of comparable quality.

Not just any mechanic will make a vid to drill it in.

Well the laws of physics can't be ignored, to let in more air, you either have to have a bigger filter with the same size holes, or, if the same size, bigger holes!

Some people don’t like this guy either, but the particle test beginning at 9:15 is interesting. The K&N didnt stop much of anything.

I would bet that the dealer would just put a new K & N in rather than spend the time cleaning it especially at shop rate. Then they would also be covering their backside by doing it. I believe Ford Performance uses the K & N to meet the required air flow for their tune. They could care less about how you maintain it. Not their problem.

Maybe it's because they installed the K&N backwards for the particle test, eh?
