Have read here that some feel the oil used on K&N air filters wrecks havoc on the MAF sensor.

My truck is a 2002 F-250 SD with the V10. Did it not come from the factory with the K&N air filter?

If it did, why would Ford use a problem causing air filter element?

 

It's not stock and allows larger particles to pass, which could increase oil usage.
IMHO

 

The stock filter will filter out more harmful dirt particles and an oil soaked filter could wreak havoc on your maf sensor. Stock air filter is motorcraft.

 

Ford didn't use a KN as stock. I have run lots of KN filters. Don't get too carried away when you oil them, run an outerwears and clean the MAF sensor shortly after you put a freshly oiled filter in.

 

Motorcraft filter is less than $15 and Zoodad mad is near free. Why bother changing to a K&N if you're already concerned?

I had a K&N and it let sand from the Ocean beach pass right through, went hope cleaned the MAF and sold it. Motorcraft back in with zero issues.

 

i learned the hard way with K&N filters if you get one here are some tips
1. after you open the plastic wrap around the filter let it air dry for several hours before you put it in
2. when you clean it give yourself atleast one full day for the water to dry and for the oil to soak in before you replace it.
3. buy the pre wrap that goes on the outside of the filter
4. clean your MAF regularly so that it doesnt get ruined from excess oil and dirt

personally i would look at AFE or some other brand and get a dry flow filter one that does not need to be oiled. its one thing to buy a cotton filter and it is another when you have to buy the cleaning kit to take care of it. me personally i get the motorcraft filters. they are way cheaper and ford designed them the way they are for a reason.

 

No not a factor filter. I have had a K&N intake on mine for almost 10 years now. No dusting, no MAF issues, no problems. I check the tube and MAF regularly. But I know how to clean and oil the filter. I also have an outerwears on the filter which helps keep it clean. The filter clamps on mine, its not a drop in.

If the drop filter doesn't fit the intake housing just right it can let in dirty air.(which is not an isolated problem)

 

Makes sense that Motorcraft would be factory. I ***-u-me d, because my used 2002 F-250 V10 had the K&N when I bought it, that it came that way from the factory. My bad!

I do know that in the early days of automobiling up the the late 50's manufacturers used oil bath filters. The switch over to dry elements was not to increase filtration efficiency, but because of convenience.

I also realize that an oil bath filter is not the same thing as an oil bath filter.

I also KNOW that I have had to clean the MAF sensor on my 136K engine with the K&N.
