What AIR Filters do you use?
« on: April 19, 2005, 10:08:28 PM »
I just did a quick comparison of what's available on E-bay to put in the stock airbox and here is what I found:

Stock filters: $15 - $25
UNI Foam Filters: $25 - $35
Reusable "Power filter" - K&N type $25 - $35

Presumably, the UNI or K&N cost more because they are a Premium brand that can be reused and give better air flow.

My question is this: if it flows better, does it not also mean it filters less?  Second: if it's reusable, do I really want to bet my motorcycle performance on my ability to clean things?

All experienced opinions are welcome - Six: Minneapolis.

I`ve been using Uni foam filters on my street and dirt bikes for years now.Very simple maintenance, just wash out with warm  soapy water then let dry and reoil with filter oil from a spray can.They actually flow more and filter better :)

   I've been using a K&N filter but after stumbling onto some testing of filters while researching air intakes for my truck I'm switching back to the stock filter. The testing showed that the K&N allowed a lot of particulate matter to pass through. Could be why the oil in my old truck always seemed dirty after 3,000 miles.

I'm using the stock filter, assuming that the bike will run best the way it was set up by Mr. Honda. ;D

Indeed Mr. Honda did leave a little to play with for those who want's to follow that route.
But the stock set up is more suited for my commuting. :)

l. The oil is what gives you the protection on uni foam and K&N filters. Without it they will pass a ton of dust and dirt. If you use them make sure you ALWAYS use oil. Hope this helps.

What Mr. Honda left out, Mr. Yoshimura makes available.

Sorry about the joke in my first post. 8)
What I should have said is that I don't disagree about improving the power, and using air filters that gives a better air flow.  :)
But the way I use my bike, commuting is one of them, with a lot of cold weather starting, and with all the fine dust we have on the roads in the spring, I prefer the stock airbox and filter for maximum protection against the dust.

I spent the big bucks and got the K&N pod filter kit for my 550k. I use K&Ns in all my Jeeps, and there IS a difference. As for the "particulate matter", it's usually owing to one of three things: 1) not oiling the element, 2) OVER oiling the element (oil droplets are pulled off the media and deposited as "particulate" in the intake), or 3) Using pressurized air to dry them, which blows holes thru the media thru which dirty air can pass.
I've never had a problem with mine, and do notice a difference in performance. I've rejetted to compensate, and don't mind the little extra maintenance once every month or so.

Thank you all for your comments!  I'm going to stick with the stock for now, I don't trust my ability to clean and oil properly, and it sounds like that is the key to making reusable filters work.

what!  six... come on now.  go out there and yank those filters if you wanna.  follow directions and thats all there is to it.  it really is in your best interest to know what makes your bike go and what doesn't.  if you tune your bike... you are in tune with your bike.

   I can't agree with that statement Darren. Any product of combustion is a source of oil contamination whatever the condition of the engine. The only source? Not at all, but definately a contributing factor. As for what filter one uses...it's all a matter of personal choice.
