Which Pod Air Filter?

[Zahos]

Has any1 heared or read anything about the filtration of the O2 rush (double layer foam type) filters? I know they flow extremely well, but have yet to see anything on their filtration abilities...

[GTS-t VSPEC]

Ken, but we all love that ricey whoosh noise, hence why we all have pods.

Zahos,

I used to have a O2 rush filter, seemed to filter just fine, but I don't really like the oil based filters, they keep stuffing up the AFM.

See'ya:burnout:

heh, I'm the exact opposite. I HATED the sound of my Trust Airinx at first (btw this is the loudest pod I've ever heard), but now I love it. My car sounded like a jet taking off when it was on the dyno! I now highly recommend the Trust Airinx for this fact alone. Just couple it with a decent blow off valve and the pod never makes the horrible horse sound when you let go of the throttle.

Cheers,

Michael

apexi filters are the best for filteration .. they have the details on a lot of websites .. but i cant seem to find them except the one 400hp gave .. http://www.mkiv.com/techarticles/filters_t...test/1/apex.jpg

my best bet is to go for the K&N element filter if you dont get into trouble with the authorities ... my 2 cents though ..

cheers !

the stock airbox is good enough for the mine's gtrs (600+HP), so its good enough for you.

HKS, Super Power Flow, nicknamed the "green hairnet" by some.

It has been "engineered to dramatically reduce inlet restrictions" and boy does it ever!. Most imports arrive with the HKS pods because the japanese aren't worried about longevity of there engines (cause they just about throw them away before the 50k mark) but they also want the best air filter for performance that they can buy!(some japanese still haven't forgiven those nasty air filters and run there car without one at all) but the best in HP is also the worst on the filter side of things!

They aren't too bad if you do all your driving on the bitumen and maintain them properly!

The HKS power filter (green one) is great. It allows maximum flow and minimum filtration which is good for HP. Unfortunately it does let dust in, but hey the japanese drive around with no air filters sometimes.

A filter that doesnt filter is called CRAP rob. And HKS foamies, are indeed CRAP. Wait till you ingest one into a turbo and see how great you feel about them.

All this talk about filters when they give sweet bugger all extra performance even over the standard. oooh.. aaah... I got 2 extra horsepower it feels so fast...wow!

[Silver-Arrowz]

I'm with rev210. I've got a mate who went through 3 different filters cause Hot4's magazine said this was best, then this was best the next year later. The air filter has only one main job, filter air. Rest is just a bonus.

[MegaGTS4]

HKS power flow filters have a mesh under the foam that has holes only about 10mm-sq. or so, So I guess that someone didn't replace the foam filter and it disintergrated (as they do perish being foam) and got sucked into the turbo. But if you replace the element every 2nd service( @ $60) there would be no way that the turbo could possibly digest the foam element.

But they are crap on the dust side of things!!

[red17]

I had one on my car when it came into the country and all it had under the foam was five or so narrow bits of plastic which kept the foam in its semi circular shape. No mesh. Mine hasnt ingested one, but ive heard of it happening. And by the look of my one, it didnt look very difficult to do.

Trying to get performance increases from air filters is for people with small bore atmo engines, if we want more power, we just up the boost so why not get the best filtering filter available on the market and put up with having 3hp less.

LOL well that's for me then! I just put an Apexi Power Intake on my non turbo R33 and to tell you the truth i noticed no difference what so ever. A bit of a woosh at high revs and that is all. I will be adding a cold air intake tomorrow but i doubt that will make a lot of difference...

Hi Guys, upgrading the filter (panel or pod) only makes a difference if the airfilter is the weak link in the chain. If the turbo is already getting as much air as it needs with no restriction (resistance) then upgrading the filter is going to do nothing.

Conversly when it is the weakest link on the chain it can make a lot of difference. I have seen a 15 rwhp gain from a filter change. That's why when I get asked, I always say don't bother with the filter until you have done a lot of other stuff. Like exhaust, dump, turbo, boost etc.

As for filtering out the crap, I follow the World Rally Championship lead and use the multi density style of foam filter from Jamex or Pipercross. They stay cleaner longer and yet have very fine inner density foam to clean out the really small grit that stuffs and engine real bad. Also filter oil is important, preferably the flame retardent kind. Don't use too much though, as it clogs up the AFM. A quick spray with brake clean fixes that problem.

Hope that made sense.

just put a Redline panel filter in and am very happy. they are the same as the HKS panel filters but without the extra cost. Picked mine up for $75.

The sound is only a little different but the power gains are defintely noticable.

Thoroughly recommend this filter.

[rev210]

Improvise,

You are talking about sound gains, not power gains. I don't know about you but I can't 'feel' 2-3hp differences.

Unless the old unit was blocked and farqared.

I went for a ride in a mates car and he has a HKS pod, and when changing gears it flutters. I WANT THIS SOUND. hehe

This sound is turbo reversion. If you want it, tighten up the spring on you BOV, then you'll get this when you back off with partial boost. If this sound is made when you back off on full boost, then your BOV is adjusted too tight.

I too love this flutter sound, i have a KnN pod, cone type, and a type 3 turbosmart BOV. I adjust it so it causes flutter when i back off with less than 10 psi boost. If i back off with over 10psi, the BOV opens and get the full PSHH noise. Apparently the reversion flutter is not too bad for the turbo under low boost levels.

Take your BOV off altogether, and all you will get is massive flutter! sounds cool, but turbo prob wont last!

[T0nyGTSt]

My car used to flutter like crazy with an old HKS gold bov + HKS green pod. Hated it.

It is less bad now with a HKS SSQV + Apex'i power intake (in a box).

I have a HKS Filter and Blitz BOV...they are a great match.

Sorry, but I love the spooling up woosh of the flter, it sounds like a turbo should, and the BOV is bloddy loud, scaring unsuspecting people on the street all the time.

[Bonkers]

Standard airbox and K&N panel - buy the servicing kit as well. Cold air intake, some but not to much noise AND it will filter the air.

Pod filters suck!
