Here is my opinion. I do NOT like oiling a filter. I personally don't think that it is good for it,and putting oil on it kind of defeats the purpose of the filter. On my commercial zero turn lawn mower that I make a living with,I do not oil the filter, as it has caused problems in the past. It's kinda funny that the dealer put the oil on the filter for me,but later blamed an engine problem I was having, on the "oiled"filter. I havn't had any problems out of oiling the filter on an atv though (not saying it won't happen one day). Personally,I use K&n filter oil on my honda rancher 420. I'm debating on not oiling the filter anymore. It's called an air filter for a reason,let the filter do the work like it is supposed to.

I have overhauled a few machines because of the air filter not being oiled. The very fine dust particles pass through the filter causing cylinder/ring/piston damage. Most of the mowers I have been around use a paper filter with a foam filter as a helper.

I think you are vastly over simplifying the purpose of a air filter. The oil serves a very important purpose. It catches the dirt that no dry filter can catch. If a filter existed that could catch those tiny little particles of dirt, it would be so restrictive it would defeat the purpose. It only needs a light coat of oil. Too much and you may have performance problems, but a properly oiled air filter is a must. I use 80w90 oil on the foam filter, then squeeze it as tight and small as I can with a shop rag to absorb all excess oil, then install.

I agree..... oil it and then try to squeeze/absorb out as much as you can just to leave an oily film.

+1. The oil catches the fine particles like toodeep also said. An oiled filter is an absolute must. Honestblades, you should look in your intake, if it's not perfectly clean then you've got a problem. And if you motor won't run with an appropriately oiled filter then you've got an air-fuel issue.

My

on filtration:

As you further restrict an opening the change in pressure across the medium and pump work increase while the volumetric and mass flow rates decrease. You basically either have to decide between good filtration or good flow, you can't have both. Unfortunantely what you need is a restrictive medium in order to filter fine particles. What you can do is get the filter with the greatest surface area to help combat this.

As far as:

-non-oiled foam, would never recommend

-K&N, Easy to clean, high flow, would recommend for COMPETITION racing applications where power output is more important than engine life. Why would you wear out your motor playing around when the extra 4-5% isn't worth the reduced engine life. If your motor isn't built, you don't NEED a K&N.

-oiled foam, Supreme filtration, adequate flow, sucks to clean. Although its restrictive, I always run the blue super nasty Spectro SX oil on my dirtbikes and clean every ride. For my less high performance stuff like the Rancher, I just go with a new factory filter.

Here's the bottom line: higher flow = lower filtration.

You're not really gonna save anything by cleaning it on this type of vehicle, maybe $200 over the life of your machine. Personally, I think I'll get >$200 worth of extra life by replacing them. Now if you're riding a 250 smoker or racing or something then I clean mine after every ride and then it does pay off to clean them.

I took your advice Red, and bought a Stock Honda Filter.....it was pre-oiled and only cost $10.50.....!!!!

That's cheaper than the aftermarket oil for filters that you got to wash, clean, wipe out & re-oil....Thanks for the advice!

the dealer. you can order them at mrcycles.com but by the time you pay for shipping it will be several dollars more than just going to the dealer.
