Just checking, is this a worth while upgrade, I have a standard MY99 Turbo which I will be putting a Scoobysport system on at xmas.

I've looked at all the rest and quite frankly i'm worried about these MAF issues, i take it that the ITG is a replacement for the existing panel filter part.

Also is this easy to fit, havent seen how you open the airbox up, do I need to make sure I dont damage the MAF, BTW where is the MAF and whats it look like! (I've heard all the discussion but cant for the life of me work out what it is exactly)

If in doubt, don't bother as they make little difference in performance in the bigger scheme of things - what's say 5bhp against 215+ ?

I seems to be about the best one on the market, but having had a MAF go on an Audi last year - with strong suspicions of the filter - I'm not bothering with changing my MY99 filter.

Having said all that, hundreds of people I am sure will swear by them. £40 filter, £200 MAF, 5 bhp - that's the risk equation !

hmm, from what I can tell people have never reported problems with replacement panel filters as all it is is the same as the normal one just a different material, hmm!

Only gains I noticed was a slightly louder induction noise, but never had peace of mind nor any noticeable power gains- & did in fact need a replacement MAF- so my concerns seemed founded(?).

Net result is I can miss the extra noise for the peace of mind running OE filter.

However, hundreds of people seem to swear by them & have no bother at all.

Perhaps that your MAF was dead anyway? Seems weird that a replacement panel filter will cause any trouble really, its the same size as the old part and is just different material. I think a cone filter which without any ducting will result in higher charge temps would cause a problem so i've decided to go with the ITG and see how it goes, can always swap back and crawl back to subaru with my extended warranty.

UHF? sold the HKS dump?

UHF

you ask me that everytime you see me post, YES FOR CHRISTS SAKE, IT WENT 2 MONTHS AGO!

maybe hes in denial

UHF

well it didnt fit his car anyway!

HKSubaru

can't find the other post silly!

UHF,

Yes, it's a std replacement for the OEM filter. It's easy to fit, but you need to remove some of the piping to get access to the filter box properly.

I've got some pics @ home which I'll post tonight for you. I've had no troubles with the MAF.

Pete Croney has previously said that any problems would be down to not re-fitting the air box properly thus letting un-filtered air into the system.

excellent, i look forward to this!

MAF's are now available as a sensor only, rather than the whole jobbie. Price is around £60ish me thinks, a bit less painful than the whole thing

Ok, its a total doddle to fit, couple of metal clippy things hold the lid on the box, the other end kinda tucks under the lip(youll see)

as for money well spent?? dunno, probably no. I dont think it did much to mine. However my theory is that its more a sum of the collective parts that makes it go better. So a filter on its own would be no use, but add an exhaust, a dump valve or whatever and the little things combine to make a collective increase. So yes!

You can always palm it off to someone else if you dont like it!

UHF

I want to get an exhaust at xmas but insurance and police might stop that (damn emissions testing round here).

UHF ,

I found spool time 500rpm earlier in an STI 7 and transition from no to full boost noticeable . You can feel the difference as a passenger too . It compliments the exhaust nicely . Throttle response is also improved low down making the car feel torquier . I'm a convert .

on a filter? i'm assuming you're talking exhaust here?

UHF,

Here's the pic of the air box with some instructions on how to replace the air filter.



1. First undo the two jubilee clips and unclip the throttle cable from the large air filter hose.
2. Unplug the small bleed valve from below the large air filter hose.
3. Gently remove the large hose from the air box.
4. Now unclip the two hoses from the top of the air box
5. Unplug the wiring from the MAF sensor and remove the metal bracket from the air box (they're just in front of my alarm siren in the picture)
6. Now unclip the two large clips to the air box lid (the ones next to the wing)
7. Lift the air box lid from these two clips and push back slightly. The air box is held in-place by a row of plastic clips at the opposite side to those clips (underneath the large hose in the picture).
8. Remove the OEM paper filter and sit the new ITG in it's place. The wire mesh and ITG logo should face upwards.
9. Next carefully replace the air box lid making sure it's secure on the plastic clips at the back of the box and the two metal clips are back in place. THE AIR BOX MUST BE SECURED WITH NO GAPS BETWEEN THE LID AND THE BOTTOM OF THE AIR BOC TO PREVENT UNFILTERED AIR FROM ENTERING THE SYSTEM
10. Replace the MAF sensor wiring and bracket.
11. Replace the loose hoses on top of the air box.
12. Replace the large hose and tighten the jubilee clips.
13. Replace the hose underneath the large hose.
14. Replace the throttle cable into the clip on top of the large hose.

Replacing the large hose is a bit of a burger since there's not much play in it. Like most things, it's easier to remove than put back on.

You could use some lubrication to make things easier, but I'm not sure how this would effect the air filter system.

Hope that helps,

Stefan

You post was great, surely we would have a SCOOBYNET FAQ Section, just for these types of great instructions. I think its time to put the my ITG filter in myself as well, rather waiting for the next service.

Nice one mate.

ozzy

No worries lads, glad it helps.

I agree about the need for a FAQ, most of these instructions get lost after a while and it's not that easy finding them again with the limited search.

I'm going to take some pics of mine when I do showing step by step, it'll be on my site which will be up soon
