I was going to fit an ITG panel filter to my MY01 WRX but I've been warned that it could damage the MAF sensor due to the amount of oil on it. Has anybody had any such problems with these filters?

Cheers,

I've just covered 10k with the ITG filter,with no problems.
MY00

 

Use to use an ITG filter. Now run a Green panel filter from TSL.

 

YET...

 

Yes, there are a few people who've had negative experiences with them. The problem isn't so much the amount of mucus on the filter, it's the ease with which the mucus gets sucked off the filter and into the engine.

The STi, K&N and Green panels are all far safer bets.

 

Listen to advice and dont use an ITG,go for a green or a JR filter which are still oiled but not to the extent of an ITG.
My MY01 suffered a MAF failure @ 15,000 miles after using the ITG from 2,000 miles.
It was covered in gunk when i removed it and @ £360 + Vat for a new one for the MY01 it wasnt a good feeling.

You have to buy the complete Airbox unit and MAF for the 01 onwards cars until they are 4 years old as Subaru wont sell the MAF as a replacement part as the do for the Classic which costs arouind £64.

 

Seeing as geniune STi ones are only £47 and flow enough air for 350bhp, it makes sense to go for one of those

 

I wonder how many owners who've posted on here saying they're running ITG filters with no problems, have ended up with some sort of engine failure, but haven't posted on here about that...

It's also very annoying that said people could quite easily influence a newbie into buying an ITG, blissfully unaware of the potential consequences. Particularly when you consider the STi is just as good, if not better, for a similar price, without the risk.

Alot of the stuff posted on here is crap, which you'd expect, as we're not all geniuses. But when something comes along with a proven track record for engine failures, I find it bizarre that some people insist on continuing to use and recommend it...

 

Quite. It's the same situation with the owners of Japanese market cars who've run on regular unleaded petrol for xxxthousand miles without their engines blowing up.

Logic and plentiful anecdotal evidence is available to suggest that the risks in both cases are heightened, so "It hasn't happened to me" is by no means a guarantee that it never will.

 

Sounds like your the man in the know.
Bearing in mind im a newbie and only had the car one for a month what benfits (If Any) would I get by changing to say a green panel or sti.....car is a MY00 uk +PPP.

Thanks In Advance

Dunno about that!

I don't think there's a great deal of difference between STi/K&N/Green to be honest, mostly down to personal opinion, or what price you can get them for. Each manufacturer will state that theirs is the best, naturally.

Edited to add, whether you'd notice any benefits or not is open to debate.

I've currently got a K&N, which is fine, but was a bit of a bitch to fit. If I was to change again, I'd probably go for the STi...

 

Thanks for all the posts guys.

Doesn't look like much of a recommendation for an ITG filter then........
......it's just a pity I've bought a second hand one already.

Perhaps because the filter has already done a few thousand miles then any loose oil will have been cleared by the previous owner!

 

My ITG panel filter experience resulted in a bill for £3,456.75

Obviously I can't prove it was the ITG filter (legal disclaimer bit ) but I strangely did choose green cotton when my new engine was fitted

 

****... ouch. How long did you run with it for?

 

**** me!

I bought my car about 6months ago, MY00 which already had a ITG fitted. I replaced a faulty MAF about 1 month ago, garage said nothing wrong with using ITG's, Me thinks I need to order the STI panel filter.

 

Methinks that would be a good idea. K&N or Green would be as good.

 

Who am I ? Drove 35.000 km now with ITG (without cleaning) , took it out once to check and inlet section was completely clean and dry......

ITG Filter sucks indeed.........lots of air

So I'm sorry , but many MAF sensors have died even when
normal filters were fitted....so I don't get it ......

 

Pretty much the same here. I'm up to 25k miles on an ITG with no problems and without cleaning it. It was a bugger to fit, though - the oem filter slotted perfectly in and out; the ITG was an extremely tight fit, which is probably why I've not taken it out to clean it

It's been reported here that it's the incorrectly fitted ones or the ones that haven't had the excess oil wiped off before fitting that usually cause most problems.

Whatever the cause, I've been pleased with the performance of mine. However, I can't help but feel that I should probably go for a different one next time. Just to be safe, like

The fact that neither of you have cleaned and re-oiled your ITG filters might have something to do with it. You may also have been fortunate to purchase filters that weren't excessively oiled in the first place. Just keep an eye on your MAFs...

 

Had MOT done on my Classic MY00 yesterday.
The Co2 levels almost passed without having to put the centre cat back in on my fully decatted car. With the centre cat back in it passed Co2 levels easily.
The problem was that the emissions test was failing on what appeared to be an air leak on what i think is the Lamda test? ( upside down y on the emissions test sheet) Spent hours trying to sort out the fault.
Finally we took out the ITG filter and cleaned the filter box and put in my Ordinary standard Subaru paper filter and it passed easily with flying colours.
Why?
I think i will post this message up in The general post area for the technical guys to ponder.

By the way, my Subaru is running much better without the itg, having kept the standard filter in. It's much smoother...very noticable.

smurfy.

 

The_Judge does have a point - a lot (not all) of failures have occured after re-oiling. Personally, I've run an ITG for more then 40000 miles in my MY01 with no problems. You need to be careful with anything you fit. If you are unsure, I would go for the paper STI version. Despite what you might hear, ITGs are easily capable of covering 60000 miles. All I've ever done with mine is check it is OK and make sure there are no deposits in the air box (which there haven't been).

Hi!

I have never had a problem and I've sold more of the JR Filter to more Subaru customers during the past 2 years than anyone, as I was the first Subaru Specialist to recognise their performance and reliability in the UK, only now are others trying to jump on the bandwagon, as they know how well we've been doing with them and how we have had no problems, unlike other brands we've dealt with in the past.
We found JR by chance, one of our Australian suppliers sent us one by mistake so we thought we would take out the old performance filter we had in our STI, as it was leaving green goo on the MAF sensor, the JR imeadiately made the car feel much livlier and the throttle response was amazing for a panel filter!

I went for the sti paper panel filter for my sti 8. Mainly down to posts on here and due to word of mouth. I can hear it suck quite a bit more and since putting the back box on too it feels a touch more throttle responsive.

 

When i had an ITG before i got the induction kit i actually cleaned a lot of the oil off of the ITG and ran it semi-dry. Never got any 'goo' in the air box, or any filter oil misting through the intake, as i thought it was too oily when i first got it

I have since replaced it with an induction kit some 2 or so years ago.

Cheers
