Air Intake setup... why cant we POD it...?

[peteon2wheels]

i have had a look in the search and cant really find any definitive answer to this question...

From what i can see there are a lot of 1.8t in the Uk that are running a POD filter straight onto the end of the MAF - just about all of them do.

Just about all the cold air intakes that i can find use a POD filter which are also oiled, perhaps just slightly further away from the MAF.

So why is it that a POD filter ruins the MAF..? A CAI still uses an oiled filter anyway doesnt it...? Reason i ask is that i have a POD that i want to adapt to the Gti (having come from an XR6T i NEEEED more power or i will go nuts). Hoping to put in some sort of CAI but not a bought version - will rig up something this weekend with any luck.

The air filter is the last thing you mod if your after power . Im running a standard airbox and probably have more power than anyone else here with a 1.8t

Australian Design Rules prohibit the use of a pod for some reason... not really sure why... it's one of those things.

Lots of people seem to run them anyway and most seem to get away with it. You *could* get defected, but then by the time the cop is asking you to open your bonnet you probably have worse problems...

In that case, would this EVOMS V-Flow (http://www.gmpperformance.com/index....ail&PID=150720)system be classes as a "pod" filter?

yeh the POD filter won't really make that much of a difference unfortunately, if you want more power that would be the last thing to do

many poeple think this...you aren't allowed to have a POD if its not secured properly. people always have pods and they are just sitting there not attached. You must also have a gaurd over the POD. they ARE legal but only correctly installed. and i think the other law for vic is your only allowed ONE intake mod, whether it be a turbo, POD or so on.

Would love to get the secured thing confirmed. NO ONE and I mean know one I have ever spoken to has given a definate reason. I have moved to a CDA CAI system because it better and more legal, but would be damn interesting to know.

ADR doesn't say no. EPA says no. Changes emissions - increases induction noise (EPA controls noise pollution as well), and changes fuel mix (EPA exhaust emissions). = illegal.

If you do install one, and get booked by police, go to EPA testing station, gets cleared and then engineered - no worries.

[peteon2wheels]

as far as i understand it any mod is illegal unless engineered, but im not really asking about that anyway.

Yes the sounds is a plus - the gti stock makes not a single bit of noise and i do like to listen to the sound of the engine.

My main question is that everyone seems to have said that an oiled filter will ruin the MAF - however as far as i can see, any aftermarket CAI still uses an oiled filter and so would be no better then a POD. In which case i will use the pod i have and just box it off from the engine to keep the heat out.

in terms of mods for power, what would you guys do speaking from experience that is cheap...

Yep it is not enclosed so it would probably be an offence.


As far as oiled filters go my CDA has made 50,000km and no MAF problems at all. Just don't go nuts on the oil when you clean it and it should be ok.
I think K&N even provide a warranty of some kind against faults.

There was a thread not long back that outlined: K&N denies that their oiled filters ruin the MAF, and would test any MAF alleged to be faulty as a result of their filters being used. Was also people who backed up this statement, and don't have issues with K&N.

I think as you can read above, most people don't think a pod filter will make a significant difference. You'll get more induction noise, which as stated, you can be booked for. Popular mod for 1.8t's is getting it chipped for extra performance.

Well if you have a look at the V-Flow there is a seal/gasket around the top lip and once the bonnet is closed it is designed to be an enclosed and sealed unit, the filter element is not exposed at all in the engine bay like a traditional pod under normal driving conditions.

Problem is still that; cop sees it's not standard, gives you EPA notice, you go to see EPA people, they tell you "not legal, increases induction noise, noise pollution."

Enclosed or not, same deal. Enclosed just means that you might get away with it more often.

[No457 Snowy]

Yeah, I think you're right, I guess being realistic, most of us on here have technically illegal vehicles if you wanted to get down to it. I think the main thing is to not drive around in a manner that says "Pick Me" and when you do mods don't make your car look like it's got a "Pick Me" sign on it to the average cop.

Probably being a "middle age" driver makes me a little less prone to being pulled over, and then your attitude can make the biggest difference of all to the outcome if you are.

All good points.

With the noise thing, I could swallow that IF and it's a big if, the noise was measured against the same measure as the exhaust volume, but no where does it say it's OK as long as it doesn't exceed xxdB.

EPA... thats a fun one.. something like removing a cat has a 5 figure fine. Again I could swallow the "it changes the emissions" IF there was a measure that said it can't exceed xxx units (in whatever they measure). I would guess there are lots of cars out there with cats that have worn to a point they don't exist anymore causing worse problems, but lets not go there. But more the point, wouldn't your ECU adjust for the increased air flow and even things out? Besides all that, does that mean forced induction is illegal from an EPA standpoint since it adds more air (and fuel)??

I'm hearing lots of reasonable opinions, but I'm still not convinced anyone is 100% right.

[D3bb4]

hahahahaha. the hell are you talking about?

There ARE figures. The year model of the car is what the figures compare to, that's why pre-86 cars or something like that can still run no cats!

I think it's more to do with the type of cars these are, rather than HOW you drive them. I've driven highly modded jap cars responsibly, and been pulled over and defected for absolutely nothing. My golf/runabout, i've been seen overtaking people in a bus lane, and the guy didn't look twice, lucky me - won't be doing that again . How many euro cars get defected compared to jap would be a very amusing statistic. The amount of people who mod their euros and don't bother with the paperwork, and don't get pulled up for it....

Discrimination!!!!!!!!!!!!!
