Re: Love my new K&N 63 Series

I'vd had a K&N on my Rodeo since new - 170k and strong. And a K&N on my KTM dirt bike. There is NO dirt in the intake. I have heard that argument many times so I lightly oiled the intake to test it-3 times. Each time when checking after first 1 month then 3 then 6-seriously-there was never a particle of dirt and the intake still had a thin film of oil. If it was true the INSIDE of the K&N would be dirty-which they are NEVER. I dont understand the K&N haters-other than the price-but that equals out over time-and even pays you after 100k I think.

Re: Love my new K&N 63 Series

I mean, if the whole allowing dirt in thing were true then why would MOPAR have a CAI that you can install as well. it's the SAME thing as a K&N. It makes no sense


to the OP I have one on my 5.7 as well along with Borla and it sounds beastly. Any plans for the back end or anything already done?

You are arguing opinion when ALL published information on the topic says otherwise, furthermore there are some using their personal experience to say they did note more buildup in the intake. im not saying its equal to driving around with no filter in iran, but its not factory protection... PERIOD!

How about arguing fact over opinion, if you find legit published info to back your opinion I would be more than happy to admit I'm wrong.

Re: Love my new K&N 63 Series

There are a TON of articles on the benefits of K&N filters. Like the most popular and winningest filter in the Baja 500 and 1000 races.
I wasnt stating on opinion-was stating the FACTS of my personal tests on a dirt bike.
It is fine if YOU dont like them but apparently a LOT of people do. I will go with the AFE Intake on mine because I like the air box style the use.

Re: Love my new K&N 63 Series

Yes the benefits of K&N oiled cotton gauze air filters.......

They flow more air than a paper filter. Install them with an improved intake and exhaust & you will make more power, especially in street and dirt bikes with remapped fuel and ignition curves or old style carburators. I run a cotton oiled gauze filter on my hi-performance street bike right now, as we speak, and I also change the oil every 1000 miles because of all the extra dirt that oiled cotton gauze filter lets into my engine!

They also allow more dirt into your engine while flowing more air!
Thats just a plain hard fact of oiled cotton gauze filters. They do not filter as well as OEM paper filters or any where near as well as modern synthetic media filters do! Every scientific study on the subject has drawn that same conclusion!

You can like them or love them all you want, doesn't change the fact that they are less effiecient at removing fine dirt particles from being sucked into your engine!

Enough already on this!

A lot of racers rebuild their motors after every race or two, so they are not worried about wear and tear on valves, cylinders, and rings.

Most street racers trade or destroy their motors before 50k miles where the poor filtration effects are first starting to be noticed.

I would never purchase a used vehicle that ran K&N air filters unless I was also planning some top end work or a rebuild.

Sometimes you are lucky and never experience a dusty environment, so you don't need a filter in that case just something to keep the mice out of the intake manifold


K&N has a wonderful effective marketing group, thats where about 50% of the filter manufacturing cost goes. Have to pay all those dweebs to post K&N love on forums.

Nothink wrong with using them if you want.

Raptor pretty much covered it, I NEVER argued sound out power, and your "proof" is professional race teams that have trailers full of replacement motors.

Re: Love my new K&N 63 Series

You are right about that-I wish I had couple spare motors-and suspensions so I could go 4wheelin with no worries.
But seriously-if K&Ns were so bad they would have a horrible reputation and not be able to stay in business.
Still going to to with the dry AFE for my oh-12 hemi tho

Re: Love my new K&N 63 Series

Do not know if it is still a claim, but K&N used to assert that as the filter got dirtier, it actually became more efficient because the dirt particles trapped in the oiled gauze helped straighten out the air flow. I had a 1947 CJ2 with an oil bath air filter as was the custom back then. Air came in through the intake and was bounced off the oil bath thus trapping dirt before it got into the engine. Nothing was disposable back then. What is my point? If it makes you happy/confident then enjoy. I am by no means an automotive engineer- I only know what I have been told and can believe to be logical- and as far as performance is concerned, unless you change the camshaft there will be no or minimal performance enhancment. As to filtration efficiency, I feel they are all satisfactory, just a matter of personal preference.
