You do realize that, to get higher air flow, it can have the same-size or smaller passages as long as there are MORE OF THEM (more surface area), right?

But that's NOT what this thread is about - it's about OILED filters. That has nothing to do with higher airflow. It has to do with CATCHING more of the dust than a (poorly-built) paper filter might. Even with the same-size or larger passages, an oiled filter might (if it's engineered & serviced properly) catch more particles because they stick & stay, rather than bouncing or sliding through.

But I'm NOT saying that a MotorCraft/WIX/other quality-brand paper filter is substantially worse than a well-maintained K&N. Only that a well-maintained K&N isn't substantially worse (and might be very slightly better in the long run) than a quality paper filter.MotorCraft is not a manufacturer, so it can't be an OEM (original equipment manufacturer). MotorCraft filters are probably not OE - OE filters are usually either unbranded, or branded as Ford. MotorCraft is primarily a branding company for service replacement parts. And like Ford parts; MotorCraft parts can come from MANY manufacturers, and those can change over the years. A MC filter made today might come from a manufacturer or factory that didn't exist or didn't supply Ford when the vehicle it fits was originally built.

This article is an interesting exploration of oil filtcrs (sic), and their manufacturers.

 

Motorcraft parts are OE parts, its just the name Ford uses for it's parts. The air filter that was on the truck when you purchased it is the same filter you will find at the parts counter at your Ford dealership. They are not just branded replacement parts made by any third party. Any manufacturer using the Motorcraft brand is licensed by Ford to do such, past or present. They are also the manufacturer who supplies the factory where the truck and it's powertrains are built. Meaning the air filter is made exactly to the specifications set by Ford. Ford probably gets a cut of the money by allowing their suppliers to sell the Motorcraft branded part outside of the dealership network.

 

My 1972 Peterbuilt had an oil bath filter on it as well as my 1974 Ford Bronco from the Factory. So no they were alive and kicking well into the 70's on Ford Vehicles (1975 Bronco was the last year) and on a 1990 692 Detroit Diesel in an Air compressor.

 

My 1963 VW had an oil bath air filter, all it had was around a half inch of oil in the bottom of the air cleaner housing. Never heard of a VW motor blowing up from a dirty filter

^^Very succinctly done. I was going to respond, but not worth the effort.

 

I used a K&N oiled air filter in my Nissan Maxima for 9 years . Never a problem. I also use a K&N oiled air filter in my Yamaha V-Max, again never a problem. I just make sure I don't over oil it.

 

No they aren't. Prove it.

 

This one is simple. The PVC recirc system is the culprit of any oil in the throttle body and intake. It’s by design. It’s impossible for an air filter to hurt your engine. It is possible for a person to over oil something though.

 

So if oil from an filter can coat an air sensor what is the best way to clean it?
