Wet or Dry Pod Filters for MAF's

[Lukez]

Heys guys im ineterested to find out more information on wet and dry pod filters for MAF based cars

Too my knowledge wet oiled pods cause big problems with MAF's as it did on my mates rb20, somethink about oil heating up the filament coz it cant be burnt off.

Now i hear that a dry based pod is the way to go, can anyone 2nd this? Who make good dry pods besides apexi?

Also how do these dry filters hold up and how do you clean them?

Info much appreciated

Thanks

Luke

i would have thought just the oil gets on the afm element over time and hinders its ability to send the correct voltage to the ecu........just get an apexi or HKS one there are more important things to worry bout me reckons.......apparently HKS ones might not filter aswell in the long run but you can replave the filter sponge for like $60

my mate has has ALOT of trouble with his wet pod filter....

he hits limp mode every 15mins of driving..... although im sure his MAF by now is ****ed

the way i got explained was that oil gets on the filament and this keeps heating up as oil is an insulator it just keeps getting hotter and it cant be burnt off.

so you cant clean dry pod filters? Just chuck em out every 60 thou kms you rekon?

yeh i agree it can be a problem, im just not sure how the oil is supposed to be combusting in the intake pipe.

sucked air is carrying the oil onto the element in the scenario, and also the air would take some off the element etc it just gunks it i spose cause the afm element sends a voltage to the ecu which is sensitive to air velocity in the afm (then calculates air flow with the diameter of the afm/pi etc)

for the hks one $50-$60 for a new filter sponge, not sure technically how long you should change it but would depend on the conditions/look of the filter - cant clean these ones

maybe others can talk for other ones

I have used both oiled and non oiled pods and never had a problem with either. no offence but the guys having problems with oiled pods are doing something seriously wrong. I had an oiled type M's (K&N) filter on my GTI-R. i simply bought the K&N cleaning kit, cleaned it, then sprayed on a light mist of the oil, wiped off the excess from the base of the filter, made sure none was inside then whacked it on. no problem.

Ditto, I have had a 320rwkw gtst with oiled pod and never a problem. I have also used the HKS dry.

My personal preferance is for the K&N type, based on the review of them done be ZOOM (I think) magazine. They found the Apexi was the best, but the K&N was a close second at a fraction of the cost. The fact that they (the K&N) can be cleaned easily is a bonus.

Two reasons I would say the HKS isnt such a good idea, firstly they dont filter as well as K&N or Apexi, (according to Zoom, tested K&N, Apexi, HKS and Blitz SUS filter) but the second, and most important thing is that the HKS filters are supposed to be thrown away and replaced regularly. If you dont the filter material degrades and can be sucked through the turbo. I have seen it, and it wasnt pretty, pitted the impeller blades. Having said that, if you did change regularly, it wouldnt be a problem. Worth bearing in mind.

Bottom line, dont be scared of the oiled type filter,K&Ns work very well and are easy to maintain, they clean out very easily and very well. According to Zoom, the Apexi is the best for filtering.

Something else that may be worth checking out, I have heard that the oiled type pods are illegal in some states, may be worth checking with your local transport department if you think this may be a concern.

I have been using oiled filters for many years, never had a problem. The most common problem is the filter being over oiled, then the AFM can be easily cleaned with brake cleaner.

PS; I was very disappionted in the Zoom test as they didn't have anywhere near all of the filters available. Plus K&N is an advertiser in their group of magazines, so I always suspect there is potential for favouratism. Especially when it is not backed up by the test results.

Zoom tend to be a bit like that, supporting sponsors.

What pod do you recommend? any problems with K&N?

I prefer Pipercross filters.

K&N are single density, so their performance drops off very quickly in a dirty environment. A side effect of being single density is that they don't release the dirt as easily when cleaning.

Thanks guys that definetly made my mind up on keeping me XStream 3" K&N pod filter......

Being the fact that apexi was the best filter in that group, being a dry type filter this would mean that you wouldnt be able too clean it?

Much Appreciated

you can clean them. It had the best filtering characteristics, not sure about air flow - they didnt really go into that much. the blitz sus filter is reported (by blitz) to be able to flow 1000hp. So saying its the best filter could be a bit mis-leading if you know what I mean. Just the most effective filtering of the group tested. Probably being a bit pedantic now...

SK, how much camber are you running in the GTR pictured in your sig? (assuming its yours)

1.5 neg on the back and 3.5 neg on the front, it varies from track to track.

Gary, Is it possible to purchase them online in AUS?

Any links?
