Pod Filter questions

[Jono]

Hi guys,

im abit of a newbie to the forum and dont really know much about engine side of things.

i drive a 2002 golf GTI and im looking to increase my inductions noise by putting a K&N Pod Filter on, rather than spending a few hundred on a full intake system.

so my questions are;

-How easy is it to install a K&N Pod Filter? ( i noticed some connections leading into the standard airbox, and that has got me thinking its going to be harder than i thought it will be to install one.)

-what is that connection leading into the airbox?

-what are the risks of putting a Pod Filter on? i only recently got the car so i dont want problems down the track...

help and advice would be much appreciated

cheers,
Jono

Wouldn't be hard to remove the air box and shove one on the end of the MAF sensor.

but what about the connections leading into the stock airbox? thats whats got me puzzled.. dont kno what it is haha

Running an uncovered pod filter is a detectable offence in NSW. Not saying that you should or shouldn't do it, but just be aware of what you're opening yourself up to.

When you say connections - do you mean electrical or just the plastic air intakes?

A pod filter will filter less gunk then the original filter, it might cause premature MAF sensor failure; and/or more engine wear. It will also suck in hotter air from the engine than your original airbox design does I think ( unless it is properly masked inside the engine bay with separating walls and has an opening to get fresh air from outside ) ...

I believe that the bad things it can potentially do does not make up for a bit of induction noise gained.

But each to it's own

umm, yeah the electrical connections. its next to the MAF but are screwed into the airbox. what is it?

[torque]

That is your piping from the air pump, it is pumping cool air into the airbox when engine is very cold to reduce the emissions...

There are very low emissions engine, I think they are Euro 4 standard. Removing that will not cause your car any harm, just to the environment.

Not really worth the percieved gains...Yes, you get the noise, but thats it. Increased intake tempreture will kill engine performance, and is illegal. Up to you though. I would look at a K&N panel filter, and a good diverter valve for extra noise.

I had a POD filter on my car when i just got it and after a few months of having the filter the MAF died from the oil in the filter. This wasnt cheap to replace. Im not sure how it would affect the GTi engine tho. Id get the proper cold air intake, it makes so so so much difference especially on an FI car

That thing is a heat sink for the ignition. Just cable tie it up near the firewall.
It was put on the air box for better ventilation.

I have BMC air intake, over priced for what it is, does bugger all but make noise, it is legal as it is enclosed.

Have you looked into the Heineken setup ?http://forums.vwvortex.com/zerothread?id=4137466

I like it, now that wud be worth doing

Thanks for all the feedback guys!! Good points in different perspectives..
Now I’m unsure on which path to go now haha

I’ve heard that POD’s can ruin MAFs, so I’m pretty worried about doing that. Rather not do a mod that’ll cause problems in the long run. Thanks Balkanac and Torque for opening my eyes about possible problems, and not let me get caught up on induction noise lol.. I’m a bit of a sucker for Induction noise, but big picture if the MAF which I’m worried of breaking.

Balkanac, what are some fairly good priced and recommended proper Cold Air Intake systems???

I’ve also considered the Panel Filter, not as much noise as I’d like. But safer approach problem wise for me anyways.. I know nothing about Diverter valves are they expensive? Easy to fit etc?

I LOVE the Heineken setup hahah might visit the bottle-o this weekend heheh

You Golf GTI comes with one stock. It is the black solenoid looking thing coming of the pipe that runs between your air box and your turbo, and has a smaller pipe running off it like a tail. You will probably know these better as Blow Off Valves(BOV's).
A Diverter Valve (DV) is similar to a BOV. Both these valves work on manifold pressure, and prevent compressor stall(a slowing of the Turbo's compressor turbine caused by compressed air in the inlet pipe between the turbo and intake manifold when the throttle butterfly closes on gear change or when your foot is taken off the accelerator).
This waste compressed air is expelled(in the DV's case) back to the intake side of the turbo when the DV is opened due to negative pressure(vacuum) in the inlet manifold.
In the cas of a BOV, the air is expelled to either the intake and atmosphere(in the case of a Dual Port BOV), or just to atmosphere.

This is a DV...

This is a BOV(both dual port and atmospheric...what I have on my GTI)

Both valves take about 10min to fit to your car, and all you need extra is 2 x 20mm hose clamps.

That minikeg intake is tempting

I'm thinking of doing what some others on the forum have done and run some piping from the stock airbox down the to the intake at the bumper.

wow thanks for all the info!! im assuming the DV is quieter than a BOV?
i can hear a faint noise with my stock DV wouldnt mind it being a little louder..
