I have been thinking about buying a ITG panel filter, just wondering whether it will make any difference performance wise? It would be going in the standar air box :happy2:
-
do you not fancy CAI?
-
....
Whereas CAI gives better performance increases, it means doing away with the engine cover and many peeps don't like to do that while under warranty. Also, unless you go the 'jonnyc route' of lots of very attractive looking but functional mods, the 2.0T FSI is fugly without a cover and slightly more open to the elements (wet).
Of the panel filters available, the ITG enjoys an excellent reputation and is a nice tight fit (said the bishop to the actress).
-
I've been fine with the ITG filter, but some people have reported oil issues as it is an oil soaked filter. The pipercross filter would be better in this respect :happy2:

Agreed I have always preferred the dry filters rather than the oiled as the latter can *sometimes* cause issues with the MAF sensor.

Cheers for all the replies.
I do fancy a CAI but i am not sure i really want the noise that comes with it, thats why i have been thinking of giving a filter a try.
So a dry filter is the way to go :rolleye:

widget said he got an increase of 15nm of torque from the new vwr panel filter. quite impressive :happy2:
-
....
I can only report that I've had my ITG oiled filter for about 30k miles without any problems and regularly inspect it every 10k miles when I change engine oil.
I want a bit more noise so I'm possibly going to change to a VWR CAI in the next couple of months.
-
widget said he got an increase of 15nm of torque from the new vwr panel filter. quite impressive :happy2:
....Isn't that a CAI and not a panel filter?
-
When you buy your ITG its a good idea to lay it on a paper towel to soak up a bit of the excess oil and give it a bit of a dab.

I thought widget had just got the panel filter Robin and not the full blown CAI as they are doing both aren't they?
-
I will have a look at the ITG and VWR ones then and give one a try. Thanks :happy2:

That's correct Dom, Widget has the VWR panel filter at present :happy2:

My ITG filter was very wet and even after removing the excess with lots of kitchen paper towels still found it was dropping oil out of the bottom of the airbox. I have since changed over to a dry pipercross one, but will we looking to move to either the new ITG intake or the VWR one once they hit the market :happy2:
-
the roc is running a vwr panel filter, its foam and not oiled and will tide me over until i decide what to do intake wise, hopefully one should be on the Pirelli next week after its had a trip to daventry :wink:
-
^^^ A Panel filter or intake???
-
....
I thought I saw an ITG intake on a Mk5 at Inters. It didn't look the part at all - Just a big exposed conical lump of foam with a crude shield.
-
If it was one Revo's White Leon then you would be correct, this is the pre-production version.
There is some improvement expected on the look of the foam surround but it's proven to be very affective so is likely to be quiet similar from what I understand :smiley:
-
^^^^
Ah yes, I remember now asking Martin to show me. IIRC I was distracted by talking to a long legged creature from Venus wearing something very tight and black.
I don't think ITG did themselves any favours by displaying that pre-production version - It looked so crude and home-made.

they are running a carbon ITG on their A3 which looks a lot better :happy2:

Will it last?? :ashamed:

....Although it's all under the bonnet, many of us still want some eye-candy there. As well as performance and also some sound.

function over form all the time for us ;-)

:P
-
I recently bought a Pipercross panel filter as it is dry .... ITG appealed but didn't get it in the end because of the oil issues - though these in reality seem more like potential rather than actual issues ....
-
I have bought a vwr panel filter it should be here tomorrow, it does say on the sight theat they found a 15nm increase so hopefully it will be a nice cheap little mod :jumpmove:
Im torn now between getting an exhaust for a bit more power and noise or getting some sportlines as they look 8)
decisions :rolleye:
-
Not sure if this would be better on a separate thread but out of curiosity what's the general consensus on filters? Pro's & Cons etc?
Am I right in thinking that the panel filter suffer less heat soak and also produce a considerable amount of low end torque than the induction kits and if so what is the real advantage of one compared to a decent panel filter. I've had numerous induction kits on previous cars and always loved the additional noise that came with them but this idea that they just don't do anything for performance puts me off buying another one for the GTi. Surely the air is already hot after passing through the turbo and other engine parts etc anyway?
It seems like the VWR panel filter is very good which sorts that if I decide to go down that line but what about the induction kits and which seem offer the best results all round from peoples experience? I've also seen a thread on smoothing the air box out inside to give even better results with a panel filter. Has anyone done this and noticed an improvement :confused:

....I don't have any experience of anything other than panel filters (yet!) but have read a lot about them. The consensus is that 'filters on a pipe' induction kits are better performers than flat panel filters, but neither represent good 'bang for your buck' like a remap does.
However, taking the principle of engines needing air, then surely aftermarket filters will improve efficiency and so contribute something. It's probably a bit like performance exhausts - They don't do much except to throttle response and sound until you also have an ECU remap. I've also been told that an intake coupled with a performance exhaust will help each other.
Regarding smoothing the airbox inside, the Carbonio ram interior is very smooth indeed. Or do you mean smoothing the stock engine cover filter box internally? - I have never heard of anyone doing that.
Some induction kits can be too noisy for some - The EVOMS is particularly raspy for example. Current fashion is not to hear boy-racer blow off dumping noises.
Filter maintenance and sound are important considerations.
Something I don't understand is why the oem air intake rams are so extremely convoluted. It concerns me that there may be a good reason as my Carbonio is the opposite.
-
I've posted the link to 'smoothing' the factory air intake box. It would seem to make sense I suppose but I really am missing the growl that come with a decent induction kit though.

^^^ The airbox design on the Mk5 is very different to the Mk4 one shown in your link so I would doubt there would be as much you can do with the Mk5 airbox.
I have tried two different panel filters (an ITG and Pipercross), and both gave very similar results.
I am now trying an intake system that attaches to the standard airbox and draws the air from the inner wing area.
However if your looking to go for the likes of stage 2 code and turbo back exhausts then a true CAI would be my choice. There is now the forge twintake to consider as well as a new intake on it's way from ITG. :happy2:
-
I'm unlikely to go for the remap at the moment due to money going elsewhere (4 year service and cam belt- bummer) so thats something I'll look at that next year when iv'e enough to pay for any parts that may or may not need replacing as as result. I want to make the car sound a bit better so will probably go down the filter/exhaust route.
Is there much difference in noise from a good panel filter then?
-
^^^ Nothing that's really noticeable TBH, but the exhaust will sort out the need for noise :smiley:
