I saw a hotrod show yesterday,and they was talking about Fram air filters ,and KN air filters.. They had this air machine ,with a plastic ball in a tube that was up right . when the machine was on, the ball would raise to the top of the tube. When they put the fram air filter in place,the ball droped all the way down to the bottom of the tube,but with the KN air filter, the ball didnt drop.
The reason why im saying anything is ,i have allways believed that seeing is believing,and i have seen were alot of guys on here didnt like FRAM oil/air breathers,and now im one of those guys now.. just my 2 cents

its a pretty cool demonstration. all of the Canadian Tires, and performace parts stores in my area have them. they let you try it for yourself. it really shows how much better a k&n is.

Air flow is only one aspect of an air filter. Another one which is more important IMO is the filters ability to trap particles. Of course this is a balancing act. A really high flow filter element will let more particulate matter through it. I have seen some independent tests that actually show that K&N is really not that good of an air filter. The thought is that K&N uses an oiled cotton gauze that is more restrictive and does not offer as much surface area as an oiled foam filter. FYI, K&N advises an oiled foam outer filter layer for their filters when they are employed for offload use.

Now dont single out Fram on this one. Any foam or paper filter is going to do the same thing. They are just too restrictive.

dont forget they turbulance that is created when the air passes through the filter, a k&n does this well yet adding another reason it gives you more power.

you might gain 5- 10 hp with going to k&n, but is letting all of those particles in your engine worth it for that little of hp? fram is such a better filter than k&n! may not flow better, but it traps better, and that is the main goal of an ail filter, to keep unwanted things out of the engine!

It's my knowledge that Fram doesn't filter anything out very well in both oil and air.

I'm trying to find a test I read comparing all styles of air filters in relation to the quality of filtration. If I remember correctly K&N beat all of the tested paper filters.

here http://www.knfilters.com/facts.htm#WORD has some info, no exact comparisons though.

Yeah, any paper filter is going to filter better than a cotton/metal mesh.

Fram filters are just like any other paper filters out there, they dont flow any better, or worse than other paper filters. I have used them alot and they always seemed to work good.

They are not ment for performance, nor are they ment to flow any better than other brands.

Ok after reading info on serveral sites I have come up with a conclusion, proving my original theory somewhat wrong. K&N filters filter 97%-99% of particles in the air entering your engine, all K&N filters pick up particles 10 microns and up, which most quality oil filters can not even manange to do. Paper filters pick up 99% of particles, but retain extremely poor flow.

Conclusion: It is certainly worth the horsepower gain to use a K&N over a Fram paper filter, the 0-2% increase in filtering you have with a paper will not be significant to your engines life span in any measurable way. The performance, cost, and economy benefits of a K&N filter are clearly better than using a Fram paper filter.

Not exactly what the topic is about, but it shows the best flowing fitlers.

thanks for doing the research

Ghetto it hard not filter particles when your still in the lab testing room...

did you see there disclaimer, " Based upon a true story"

Ghetto, im not picking on you but, You also listed a Kn website for tests.. I havent looked at it yet, but let me guesss... did you know Im a psychic also?... Let me see, uummmm ummmm huummm, I see an image.... hummmmm its a KN filter test.... ummm it shows..... oh my! it shows they are the best filters made on the planet.... hummm i am seeing test numbers too.....

brainsboy not to pick on you but if you actually read the K&N site you would have seen that there was no test showing K&N's filtering abilities in comparison with other brands. Only a micron level that their product catches, which the numbers they show on their site are truthful. I could have posted other sites showing the same information but to me it seemed redundant.

I couldn't find a disclaimer saying based on a true story? Could you please tell which of the two sites I posted contained that and where it is.


If anyone is in disbelieve do research and post info.



Mike

Ghetto,

I guess you didnt read the section on independent lab tests, .... And you must of passed the section where they commented on SAE poor requirements. Im not looking for a fight here mike, but lets not fall into large companies marketing....its all sales... You could probably make toilet paper come out better under certain lab tests and conditions. If you think there numbers are truthful, great. I can probably find a site with different numbers for every site you find thats the same. Numbers are numbers, heck throw in some odd numbers like .00571 then they must be true, find two sites with the same info and its from the bible.

Kn may be a better a filter, Im not against it, but everything you have stated is from their site. Im sure its a great filter, but I still dont believe it all. Show us some non-profit organization tests.

The part about based on a true story was joke. because every one always believes what they read. I remember when CD's came out, they were advertised as a NEW SCRATCHLESS, un-destroyable way to have music.... so much for those facts..

Im not attacking you Mike, I'm attacking large companies making it hard to know the truth from fiction when it comes to us consumers and cars. These companies have gotten carried away with creative ways to bend the truth and nothing governs them.

I think k & N is over-rated.IMO

im sure it is, but every thing is these days.
