I thought it would be interesting to do a comparison of the K&N drop in air filter vs the OEM paper air filter:
















Filter media comparison:










Summary: K&N filter media area = 270 SQ. " OEM Paper media area = 1485 SQ. "

 

Ok, but which one is better performance wise?

 

Wow. Real testing. Good job.

I'd still run the K&N.

 

K&N by far

 

Proof?

 

I love mine.. thats and its cheaper then replacing the paper ones every what 4-6 Months

 

For dirt and oil, YUP!!!!!!!!

 

So it performs better because your love it, real solid proof you got there!

 

lmfao that wasn't proof.. i don't have any its just cheaper in the long run..

 

A negligible amount of dirt and it will only pass oil if you are a moron when you maintain it.

 

Lol just because its cheaper doesn't mean its better. Dino oil is cheaper but look how many people are paying extra for synthetic. Just playing devils advocate here

 

paper just looks cheeper anyway. Id get a K&N

 

Someone have access to a dyno for free? We need to test this **** out now..

 

I wish I did, I'm curious. For me the K&N has a bigger risk with over oiling it and screwing the MAF up. For those very few extra horsepower I'll just stick with the paper one.

 

Its not that hard I've had a K&N in all 4 of my Vehicles

 

Evidently there have been complaints about claiming to increase horsepower,
which is a lie.
I noticed the words have been changed to: "Designed to improve horsepower & acceleration"

 

Whens the last time you had to hood open on your vehicle and some guy came over and took your air box apart and said hey you air filter looks cheap. LMAO

Same here, if the paper ones where so bad and the K&N ones are so good wouldn't Ford put them in there vehicles from the factory????

 

Placing them side-by-side and comparing filter media square footage does not accomplish anything. That's like saying an apple tastes better than a grape because it is bigger. They are two totally different devices that work in totally different manners. This comparison proves nothing for either side.

 

agreed

 

I disagree, what it does prove is if the K&N flows more air with that much smaller filter media area, it's going to pass more dirt. This was proven at races like Baja, the reason the K&N was developed! The OEM paper filter would plug up in no time, the K&Ns wouldn't! But since the airfilter isn't what limits the amount of airflow into the engine, you could use chicken wire, and you wouldn't get any more flow over the OEM paper filter!!

 

Jesus I can see this thread is going to go downhill quickly.

Here are some more thorough testing done by people. The K&N Filter will have less because it doesn't rely on the physical paper to filter. More the oil, that is why it is renewable.

^Not found

I don't use a filter

Why try to decide between the two? I just refuse to pay for either one because I dont know who is telling the truth.

So I win they lose

 

I always hate these OEM is better threads... Always telling me stock is better than this and that... This forum i snot about running a stock truck. It was developed for people who wish to modify their vehicle to their liking and the way they want to run it. If they keep it stock then no big deal but if they spend hundreds or thousands or modifying it to what they want you shouldn't give them crap for it...

 

Ok by saying this then you are saying I need to buy the big fat cheap roll of paper towels instead of spending the extra dollar on bounty because it has more sheets. Nevermind the fact that I can ring out and reuse the sheet of bounty.


More is not always better.

 

Never thought of it that way. I run a K&N, formerly a CAI, now just a drop in and never had any trouble with either. The way I see it, if it was harmful for your vehicle, K&N wouldn't do much business would they? This test seems like a waste of money and two perfectly good filters to me.
