ITG maxogen - new enclosed filter information.

[jedi-knight83]

Finally snapped up an induction kit. 1 month old ITG with less that 400 miles. The bonus is it comes with the new cold air enclosed filter as well :) which is not going to be sold publicly via traders according to the chat I had with ITG.

I have both set up's so it gives a good chance to do some comparisons.

Visual Difference

First thing is obviously the looks. The ITG maxogen seems a bit marmite and I can see why. For approx £350 the foam heat shields aren't what I would call a quality product. However the performance of this intake is well documented and I'm not entering any engine bay show and shine competitions any time soon so it wasn't something that put me off.

The original ITG intake (shown on an A3 2.0tfsi)


The "gen2" / "revised" / "enclosed" intake (as it has no official title I'm sure it will be called many things) Uses the same turbo connection hose, MAF housing pipe, expander hose, heat shield pipe and back 90 degree elbow hose as the original ITG intake. As I've said, ITG are not planning on releasing this kit as a package so you would need to have these parts from an existing ITG intake already.

The new parts are listed below (thanks to bigmig95):

ARAB65/84XL filter

STAB99 air filter housing

STAB99VWRCAISSPA slam panel adapter

Modified STAB99VAGTSIMB mounting bracket assembly

The revised / enclosed intake (again shown on a A3 2.0tfsi)


Looking closer at the actual filters. I removed the filter housing from the new filter (on the right) to show the difference

New style on the right. Old style on the left



Cost
Again, because its not an official system there is no set cost as yet for the upgrade parts but its likely to be around £200 for extra parts.

Fitting

If you already have an ITG fitted you can remove the filter, the front 90 degree elbow hose and the extension pipe that is screwed to the engine block. These are not used in the new kit.

First you need find the hose and valve shown here. Remove the hose clip and pull out the valve and shorten the hose by approx 10mm. then push the valve back in and re do up the hose clip



Then fit the new bracket. I used 7 of the supplied washers to lift it up to the correct height for the MK5 GTi



You may then want to add some protective wrapping or cut up some flexi conduit to protect the hose that the bracket ends up touching



Then fit the slam panel attachment in place and then slide the filter canister into the hose and then bring it forwards into the slam panel attachment (I have not yet got the correct slam panel part so no photos of this bit yet. This is just theory and I will amend this part once I have it fitted.

Aim to fit a good 30mm+ of the canister pipe into the rear hose



Then use the supplied strap over the canister pipe to hold it in place



Audible difference

Darth Vaders evil twin disappears with the new enclosed filter. You can still hear a slight whooshing on acceleration but to my ears is barely any louder than the stock intake and the whooshing and hissing on part throttle of the open filter is vastly reduced if not completely eradicated.

I will try to record engine bay and cabin audio in due course.

Performance

Something which needs much more testing and a rolling road but here are the results of some crude on the road logging sessions. remember this is without the slam panel adapter in place so the enclosed system was still probably sucking in hot engine bay air. Again this will be updated in due course.

I did 2 runs (1 in either direction) on the same stretch of road with each filter set up (so 4 runs in total). The runs were no more than 60 mins apart and the outside temperature was 19.5 - 20 degrees according to my dash. Run was done in 3rd gear on a DSG car

Incase the legend is too small to read.

Blue = open filter run 1
Red = open filter run 2
Green = closed filter run 1
Purple = closed filter run 2

Thanks for looking.

This first post will be updated with new info as time goes on.

I would be very interested in noise levels of the enclosed part?

i will try to compare by ear to the best of my ability and report back.

I'll be interested to see if there is any benefit / downside to the enclosed version. I guess getting a cold air feed is better than the open filter?? but it looks like a slightly smaller filter from the pics.

Anyway collecting sunday so will know more then.

I am not sure the size of filter will matter upto a point?

I could be wrong.

The noise levels of the 'standard' Maxogen is far too much for me.

You did well to get both in the deal.

I don't want to know but did you get them for a good price too?

£350 for both which is a tad more than a brand new itg on its own. I had set a max budget of £270 for an intake but its practically new and i was curious about the new part so figured it was worth the bit extra.

.
My understanding from what I have learnt about the Forge Twintake, is that surface area of a cone filter does make a difference: More surface area = more gain. However, I don't know how substantial such a gain would be.

An open filter will certainly be noisier than a closed one.

Personally I very much prefer ITG's closed version as far as looks are concerned.

[jedi-knight83]

im guessing its the same enclosure (all be it slightly modified to extra length) as the mk6

why are the mk6 inductions always much cheaper than the mk5 too?

More people modding MK5's easy money 

Another year or so im sure the Mk6 price will start to rise 

[jedi-knight83]

another plan for the open itg version was i wanted to make a custom fibreglass enclosure along the same lines as the volant enclosure that takes air from the centre scoop still.

Fitted mine last weekend.  Little bit more fiddly to fit with than the open filter system.  Some minor hose modifications to be carried out due to clashing with the cannister.  The hose pictured needed about 10mm cutting off so this valve didn't clash.  Coolant hoses underneath the cannister may need some looking at with clashing / rubbing. 



You'll also need to ensure that there is minimum safe engagement in the existing maxogen hose (if converting from the open filter system)  The air in end need to be engaged as much as possible into the grill / slam panel adaptor plate,  if this is just engaged by a few mm engine movement may cause the nose to drop out the panel adaptor.  This may be more of an issue on DSG based vehicles under aggresive gear changes.  Mines a manual and I stuck about 35mm into the hose to make the air in nose engagement half decent.  Hasn't come out so far. 



I'd be really interested in flow figures from a back to back test on these two ITG variants.  From a bums on seats perspective there seems no difference to me personally (Revo Stage 1 GTi, KO3) . 

The noise difference is the major improvement.  My open filter was driving me mad but this is so much quieter, still the faint noises from the turbo control system but without that intrusive noise at part throttle of the open system which wasn't my cup of tea 

Thanks to pirelli08 for putting this thread on that led me to purchasing the new cannister arrangement

Omly problem now is her indoors likes driving it now it's quieter

Oh you got the enclosed bit too?

How did you get yours?

Apparently it's the front part of the mk6 intake

Picked it up today. All looks good.

Glad u brought a intake,last week we where both after a twintake in the sales section

Dropped ITG as soon as I saw Pirelli08's thread.  Spoke to them nicely and they were very helpful.   

For anyone else the part numbers to change from open maxogen to cannister type are:

ARAB65/84XL filter

STAB99 air filter housing

STAB99VWRCAISSPA slam panel adapter

Modified STAB99VAGTSIMB mounting bracket assembly.

Let us know what you think when you've fitted it   

[jedi-knight83]

I'm happy to do a vagcom maf log of the stock / open / enclosed of someone gives me instructions on which blocks to log and how to display the information etc.
