MK4 GTI Intake/Airbox

[Stocky789]

Hey guys,

I am looking at upgrading the intake setup on my missos GTI just for some extra noise and air flow but my question is what are these plugs for on the airbox? What do people do with them once they go a straight pipe to a pod filter, are they important or can they be disconnected with no issues?

AFAIK they are simply placed there to cool it down with the flow going over it.

That's the ignition control module / ignition amplifier, they're there because apprently it gets pretty hot, and there's a heatsink on the inside of the airbox for it, so the intake air cools it down. Apparently you can relocate it into the engine bay but most people advise you put a bigger heatsink on then.
If you cook it you'll have to replace it $$$ or get a kit and covert it to newer coil packs, usually the 2.0t packs, also $$$.
You can't unplug it because it's a direct part of the ignition, no spark without it.
I've seen some CAI's modified to put it back inside the piping, bit of work but maybe the safest option

With my intake setup, I have a metal box which I made a hole in to sit the icm in.

Alright, I didn't take a good enough look at it, so it has nothing to do with airflow or anything VW have just mounted it there for airflow?
So i can relocate it elsewhere if removing the airbox.

What do most people do when upgrading there intake?

Awesome fellas
Any issues getting just a MAF adapter and putting a pod filter straight on it without the piping?

[Shmulzie]

shouldn't be a problem, my setup is like that

mate don't waste your money on CAI
won't give you any extra air flow, in fact your g/s may drop and the noise becomes annoying after a while
I've tested the stock air box vs short ram vs similar intake on the previous page on may car, I remember that was the worst one.

You better off getting an oversize TIP

Yeh I don't care much for any performance gains just want it sounding a little more "turbo" if you know what i mean
