Mine needed an adaptor plate, i got that from autobarn.

i believe the apexi filter comes with the adapter to suit.

unless 33's are different to mine u will need an adaptor of some sort or you could run some screws through - i wouldnt, but some ppl have. Depends on filter setup though, you may not be able to screw into anything secure enough...

I got an O2 Rush and it bolted straight on to the AFM. Couldn't be easier. Just make sure the pod kit you get is to suit an R33. No mods required. Just be prepared for the sound! I thought I must have forgotten to re-attach a pipe or something when I took it for a test run. Love it now though!

pod filter + exhaust, i'd say yes the sound will make heads turn...I am going to make up a cai box for better cooling of intake air and to quieten the thing down a bit...you can clearly hear it with the windows up and stereo on too!

[it sounds like a have an aftermarket BOV, but i dont and personally wouldn't waste my money]

Dude, if you bought a *kit* that means you would have got an adapter [correct me if im wrong] with it to suit your car [r33] ~ I haven't modified anything on my car to fit a pod either. Your wording is likely to confuse someone that hasn't fitted a pod filter before!

Unless you can buy a pod with the screw holes already there? anyone care to enlighten me on this? Maybe 33's are different? I doubt it though...even commondoors need an adapter why would 33's be any different...

Yeah, I have a UAS cold air box, Pod filter + exhaust and aftermarket BOV which was on the car when I got it. I got my girlfriend to drive the car up the road away from me then towards me and you can hear the turbo spool up over the exhaust. As nismoR34 said it definately turns heads when the turbo spools up. Don't know whether the box quietens it though? I like the sound, others hate it. Its is all personal preference.

It still seems quiet to me. My previous car, a 72 GT Clubman mini, had twin SU's hard against the firewall, now thats loud!

I do like the sound too but when you are turning heads ~ sometimes those heads belong to Police/EPA/etc, and can be asking for trouble...which begs the question, are any of these things legal?

PODs: according to EPA you can have 1 intake mod, a pod thats NOT foam is okay but not the oil based from what I have heard. But what about police / vic roads do they care about pods? or the noise? *shrugs*

BOV: I am not 100% sure but I know people that have been told off for using them, and have heard that they are illegal if vented to atmosphere.

BC: An intake mod, so when used in addition to a pod [or after/m intercooler] it is not legal [only 1 mod allowed].

I think we need a FAQ section for these issues, written by people who have either obtained info from the relevant authorities or are the authorities themselves.

The O2 Rush is all one piece! There is no adapter piece. Just pull it out of the plastic, grab the nut and bolts from the AFM which bolt it to the original air box and bolt on the pod. Job finished!

yeah ok then - the adapter is built into the pod ~ same as unifilter I believe...but they don't cost $30 like my pod either ;)

I personally can't justify spending 200-300 dollars on a pod that doesnt do that much to increase performance [compared to the cheaper ones]..call me a :shake: I dont care!

i read at the blitz UK website that expensive and cheap pod filters are different in the sense of the amount of air they let through.

then, i read at another thread in this forum that the pods that let a lot of air through dont filter the air much and that causes a lot more deposits in the AFM.

is this a compromise that we have to live with?

ps. the blitz filter was made from a metal mesh and like a few others, claims that its the best. but if you tell me that a $30 filter will do the same, hey, i'm not gonna spend $300 on a blitz!

I have read all of those tests on filters and personally dont see the point in spending $300. Sure they may look good or flow a bit better or even sound a certain way but I am happy [as are other friends] with my $30>40 Simota etc filter.

Stock turbo and engine only need a certain amount of flow anyway [there is such a thing as too much I believe], a pod provides a better flow than a panel - this has been proven. A lot of the expensive pods seem to fall into the *oil* category too which makes them non-epa compliant [illegal]. So no foam and no oil to be safe and legal...

If you are like me you won't let your filter [pod or otherwise] get dirty anyway ~ if it does and you cant clean it, buy another one! At $30 odd dollars a pop you'd be lucky to spend anywhere near the cost of the others, maybe in 10 years or so...

I have found this book very useful *21st Century Performance* by Julian Edgar. A lot of his articles from the book are found at www.autospeed.com.au plus other tests / reviews...buy the book or read through the website for info on air filters / turbos / boost / exhaust etc...

oh yeah, just be sure to read the packet the filter comes in > some of the really cheap ones [not simota] say *not suitable for use in turbo cars* I have come across this only once [a/barn], the filter will probably be fine but if it does stuff up - you can be sure there will be NO warranty coverage!

      Done, I'll do mine soon too - whenver I take out the car next. I can cheat and make it quieter by turning off VCT at idle too - but I lose the braps

      All trim back in wired running driving. Few things to follow up on but not far off the return to the road. att.6HN4wP38LTIOISkhA8eACoBFqzfgQMahZPLA8ut0pqE.mp4 att.w2q0ux2PGuqgQTj2Os13cNHQtqcSEcCAhD_CAXy_IQM.mp4

      The trouble with phone apps is that they really do not know the sensitivity of the mic on each specific phone, whether there is some sort of cover or skin that can change that, etc etc. So the readings off them are not calibrated. You certainly couldn't be sure that you were even within 3 dB. I have the same app on two (actually more than that) different phones/tablets and the readings in the same room at the same time are never the same. I don't mind the apps - they are as useful as a dyno - if you're testing for delta from thing1 to thing2. But not to try to generate some sort of absolute value.

      I'm gonna use the "Sound Meter" app from the Google Play Store and as close as I can bother to these procedures: 4. TEST METHOD FOR ALL VEHICLES EXCEPT PRE ADR83 IN-SERVICE GOODS VEHICLES AND OMNIBUSES 4.1 Microphone position 4.1.1 The microphone shall be directed towards the orifice of the exhaust outlet and shall be supported by a tripod or similar device not providing excessive acoustic reflection. The general requirements for positioning microphones are shown in the Appendix. 4.1.2 The nominal axis of maximum sensitivity of the microphone shall be substantially parallel to the test site surface and shall make an angle of 45 degrees ±10 degrees with the principal direction of gas flow from the exhaust. 4.1.3 In selecting the 45 degree alignment from the outlet of a motor vehicle fitted with two or more outlets, only the angle resulting in the microphone being farthest from any other outlet must be used. National Stationary Exhaust Noise Test Procedures for In-Service Motor Vehicles Page 3 4.1.4 The height of the microphone above the test site surface shall be equal to that of the orifice of the exhaust outlet ±25mm but shall not be less than 200mm above the test site surface. 4.1.5 The distance of the microphone from the exhaust outlet orifice shall be 500mm±25mm. 4.1.6 [Relates to vertical exhaust outlets] 4.1.7 For vehicles fitted with one exhaust outlet the microphone shall be placed so that the greatest possible distance is achieved between it and the vehicle. 4.1.8 [Relates to multi exhaust outlets] 4.1.9 [Relates to multi exhaust outlets] TLDR: 200mm off ground 45 degree angle relative to exhaust flow 500mm from tailpipe exit. (I probably won't use a tripod) Here's a photo, cause I read the instructions wrong myself.
