The main difference between the K&N oil and the "Uni" oil is that the K&N is squeezed out of a bottle. The Uni oil is sprayed out of an aerosol can. It's the propellant that makes it go into the foam better and "appear" to bond better. This doesn't mean it's "different". Like I indicated, you can use the stuff out of a squeeze bottle. You just have to "kneed" it and soak the excess out. For anyone going from the K&N type to the foam type and already have the cleaning kit, it's a bit of a waste of money to get the "new" cleaning kit. Of course, if it'll make you sleep better at night, then get the brand that is offered by the company who sells you the filter. They'll love you for it too. Great marketing. (Ever wonder why Honda only wants you to put only "Shin-etzu" grease on your rubber seals and why GM wants you to put only Silicone Emulsion on theirs? --- Same idea.)
Besides, the original poster said he has the type that resembles the K&N.

ps. Believe it or not, people have successfully sprayed their newly clean air filters with PAM. All it does is provide a film of oil. I somehow doubt that air filter oil marketers put in any specialized magical ingredients to help the oil catch dust better. As long as you're not coating the filter with axle grease, any light oil would work.

 

It's not about any special magical ingredients putting the right kind of oil on a Foam filter is very important process...the wrong kind of oil will "drains off" of the filter element. Leaving spots of the foam dry where dirt will go through. "Foam filter oil" will stay on the element for months(maybe years?) and the element will still be moist to the touch. Remember, the oil stops the dirt. The filter just holds the oil.The desired process is for dirt to stick to the oily foam strand. Then the piece of dirt soaks up some oil and the second, third ,forth and...the 14th piece of dirt will stick to the first piece of dirt. With a light oil there isn't enough moisture for that to happen, so the dirt will eventually go through. The uni filter oil is a heavy weight mineral oil mix with non drying glue agents. The K&N filter oil is a lighter weight mineral and organic oil with special polymers formulated to work in combination with the cotton fabric. Uni filter are made out of Foam material...K&N filter are made out of cotton gauze material. Each require they're own type of oil to work effectively...


P.S. I don't think you would put unleaded gas in a diesel engine??

 

As it turns out, K&N also make foam filters and guess what? They use the same cleaning and oiling kit as their cotton gauze filters:

Look, I'm not going to continue this debate. You have your beliefs and that's great. You are entitled to hold them. My advice to the original poster still stands.

 

So there




Just back to the original, we are all assuming that the Mugen filter is a K&N or is there some thread to prove it?

 

Here is the info on the Mugen filter:

It appears it's of the foam variety.
Now I'm going to give you the "official" stand on this. (My DISCLAIMER, if you will and my concession to Topcat ). If you have a Mugen filter, you should be using the Mugen cleaning/oiling kit.
Oh, in answer to your question: No, the Mugen is NOT like a K&N. (Sorry, I should have confirmed your assumption right from the beginning of your thread.)

Although K&N says you can use their oil on the their foam component of their filters (2 stage), Mugen will only recommend the use of their product. Doing otherwise could result in damage to their filter.
"Experts" on 2 stage filters (gauze and foam) state that only the gauze part should be oiled. This is in contradiction to what K&N has indicated. However, this is most likely due to consideration to airflow characteristics as is it known that oiled foam will be more restrictive.

 

I agree with xviper...I use the K&N cleaning kit for my Mugen CAI.

 

Hehe, thanks for the back-up. Appreciate it.

But "officially", I can't make this recommendation.

In recent years, all my "How To's" have been preluded with this:

DISCLAIMER: The procedures, methods and products written up here was for my circumstances only. I make no assertions that your results will be the same nor do I claim that this is the best way to do it. USE AT YOUR OWN RISK!

And to protect myself (and maybe even this site) I must attach this here, too.

 

, NP!

Even an idiot can do this one right.

 

 

As it happens, I just cleaned the filter in my Comptech CAI. It's been a year, and the time has come (there were leaves in my airbox! ). I used the K&N cleaning kit, and it worked fine. Just rub the oil into the filter and all it's all good.
