umm.. they are cheap... don't filter so well (but keep out rocks).. and the area of actual filtration may be smaller than a paper filter....

paper filters have accordion shape to maximise area.. (as do other ones), but paper filters are actually not that small.... and most of the time, the filter is NOT the biggest restriction..

unless you actually measure the pressure drop across the filter (and made sure it was not just the airbox), then there is no need to change to a pod filter...

If I find an airbox that suites me well i'll switch back to a panel filter, but K&N filters are pretty cheap as are the clean/oil kits.

oiled are expensive and need to be cleaned and re-oiled regularly.

i would say oiled-foam would work the best seeing as 99% of dirt bikes have them, opposed to the paper element ones. motorbikes see much dustier conditions than most cars do. one other downside with oiled type is that they are messy. some of the oil usually ends up dripping off.


in terms of price, i dont think there is much difference. uni filter foam types are only $30 and a big bottle of foam air filter is about $20-30. how much is a quality K&N? about $70 ?

the foam one would easily last a year...you just have to clean the foam in degreaser (quickly), clean in water, allow to dry, then apply the oil. i do mine every 2 months or so.


how long do paper filters last?


being that they are nearly equal in every way, i would choose the oiled-foam type because it (possibly) offers better protection against crap

K&N filters are often on special at ricerbarn.

Personally i'd rather get an apexi pod, i've heard they are good!

that's what sells pods


Brett, good points re:dirtbikes....
for cars tho, how often are people willing to replace or clean their air filter? t least with a bike it's more like part of regular maintainence whenever you go out for a ride?

[brett_celicacoupe]

a road driving car wouldnt need a foam air filter cleaned that regularly.

thinking about it now...the uni filter on the 1g was actually in there 6 months without being cleaned. there was a bit of crap on the outside but there was no signs of dirt getting through it.


what i think is funny is the people that get the foam filters and then dont oil them. foam on its own does absolutely nothing - apart from stop rocks and boulders. the oil does all the magic.

and yes, the other concern with foam types is need for regular inspection to ensure they arent breaking apart.

All this talk about filters reminds me that my K&N could do with some cleaning...

quoted once in victoria

"pod filters are illegal especially oiled ones because the oil is flamable and will cause engine fires under extreme heat" strangely i've never seen this happen and as far as i recall, the boiling point of oil is a lot higher than the temp of the engine and exhaust manifolds, and that oil by itself isn't flamable..

*meh* from the other thread about this, there's always the issue of flow v.s. filtration. crap filters would allow more flow and good filters would hamper flow... the tradeoff was mentioned, however the solution is to have a very big and good filter..

To back you up there, the girlfriend's Excel is leaking oil directly onto the exhaust manifold. Apart from a stink and some occasional smoke, theres nothing going on in there. You would need to get the manifold hotter than the fires of hell to ignite the oil.

id like to see air filter oil burn

My K&N was worth $80 new, I picked it up for $45 off RA65 Sleeka (never or barely used) and the adaptor cost me $26.

My original airbox in the MA61 is supposed to have an attachment that goes from the box out to the right infront of the engine to help get some cool air into it only when I bought my supra it never came with this attachment So I just had an air box with a hole in the side of it so it wasn't really getting any cool air anyway. And the filter in there looked old a bit dirty so I think I did notice enough difference so far to warrant it. Haven't seen the filter catch on fire yet though

That can be arranged



as for the real topic at hand.... i think we have covered it enough to say that it really isnt a performance gain.

fwiw - i run a $20 autobarn "special" filter on my 18rge. I only use it because it was the cheapest and easiest way to stop rocks and other crap entering and potentially munting my engine. It is far from a performance modification......


p.s. MrShin - i find your product intriguing, i wish to subscribe to your catalogue.

[brett_celicacoupe]

i might re-phrase that.

id like to see air filter oil spontaneously ignite purely from underbonnent temperatures

is that how you bore out your engines?
