Has anybody had any problems with their Carbonio?, mine is only 1K old is filthy, AMD are not happy with them anyway and have actually recommended I take mine off and put the standard air-box back on.

I have a 1.8T with AMD Stage 4 big turbo upgrade including full Miltec exhaust & Cat, also a Forge FMI and all the Samco Hoses & Recirculating DV etc.

I had heard about the Carbonio and it looked to be a good buy to get a few more BHP, there are all the rumours regarding Air-Mass-Meters etc, but thought I would give it a go.

I?ve had it on for about a thousand miles, possibly less and the air filter is absolutely filthy, obviously the filter is in the perfect place to get cold air, but it also looks to be in the perfect place to get dirt thrown up from the road.

One down-point that I must admit I?m starting to get a bit board with is the big woooooshh and tissst as the turbo does its thing amplified through the induction tube, it sounds like a boy-racer Escort Turbo with an atmospheric DV.

Anyway AMD have never been keen on me fitting it, not only with he possible problems with the Air-Mass-Meter but with the way the induction tube forces the air in rather than the car sucking it in, now that the filter is filthy they have suggested I change back to a standard air-box.

They state that the VAG air-filters are good enough for 600 BHP tuned RS6s and if they had found an aftermarket air filter/induction kit that was up to the job they would sell/recomend it.

I don?t want to turn you off fitting yours, only am interested if anyone else has had any bad vibes as the Carbonios are relatively new.

One thing I would advise if you do fit yours is to cut the backs out of the front right grill so to let some air to the filter.

I had mine fitted for about a year with no probs and when it was removed the filter looked not far off as good as new, I would think twice about removing the back from the front grill as this should only increase the chances for dirt and water etc to reach the filter.

Thanks for that useful info.

Superchips told me I was wasting my time too, but I was suckered into modding my car "to the max" so added the CAI onto a large order at Awesome. With the diesels, they have less demand for air so the point you make about standard airboxes is all the more true.

I've had it since April and have had 2 aborted attempts at fitting it, beaten back by the battery and headlamp clearance both times.[:eek:)]

I'm surprised induction kits per se are not AmD's bag, as for instance both Ed and Gary Handa (hello Gary???) are inductions kits.

I have fitted Hofele vents which will channel air effectively onto the filter once it is installed.

See what you?re saying about taking off the grill, it must have definitely contributed towards dirtying my filter if yours is clean and it?s been on for so long. I just couldn't see at the time how the filter would be beneficial if it was stuck behind a solid bumper.

Edd at AMD has actually put a standard air-box back on as well and Gary?s car doesn't count as nothing on it is remotely sensible.

The thing is why would VW (and Audi) spend megabucks on putting the air-box and induction ?passage? in that position if it wasn't the best place? Cant help thinking that even with its indirect route, the filter does get clean air rammed in from the grill and the paper filter does not harm the MAF.

AMD state that the air-box creates cold dense air before it gets sucked in (which the engine likes, almost like needing back pressure in the exhaust), the Carbonio just literally rams air in. They've also said that they had a Pipercross kit (identical to the Carbonio) sent to them to test and sell for the R32 and within a couple of weeks it had ruined the MAF and the power was down, so they put the original air-box back on and sent the kit back with a bill for the MAF.

What AMD/Edd/I am going to think about is some kind of hybrid using the standard air-box and filter (so as to keep the MAF happy and keep the cold dense air theory), but use some kind of induction tube to add extra air to the air-box. My theory is to use one of the Hofele type vents with a flexible tube running off the back to the air box, sort of adding another induction 'passage' like the standard one from the grill.

A search on here will reveal plenty of info as this has been done before. Search under GaryM as he made some good posts on his findings.

As for the CAI I ran one for 10k with the grille opened up and the filter wasn't excessively dirty. Is your arch liner secure and is the bottom of the filter above the bottom of the front valance?

The solution to your plan for a better air feed to the airbox could be to use Marley mini-guttering and jointing. R1GTI has done this I think, and even the mighty MRKIV utilises some Marley PVC trunking IIRC.

Yup.. Gary did his own custom CAI using 80mm tubing, iirc. Correct me if i'm wrong please Gary [:)]). A few people have done this.

I have closely inspected MrW's job (it was on here til the server move) and it definitely makes an improvment. His is an upsoluted AGU, no huge turbo's etc, but it seems to be worth doing. It's also damn near silent in operation, quite different from the carbonio [!]

I have some flexible tubing from a pond parts suppliers to do mine.. soon [:I] it's about 60mm diameter and will run from the front left hand grill, up into the airbox, smooth the baffles (in the airbox) and then place my green panel filter into the box.

Perhaps AmD can explain why many many std cars suffer failed MAF's.

stock airboxes and paper filters...

I have run Green filters for 50,000 miles or more, 35,000 of which were >300bhp. ZERO MAF failures attributable to filters.

Airflow increase from aftermarket filters is well documented, as is full on induction kits.

Now.. choosing an air source however, which may be turbulent air, can upset MAF readings. This is true.

I've run induction kits for 60,000 miles on mine, a carbonio for about 30k of those. Zero problems, other than it's a female dog to fit, and I still love the noise. Zero maf problems.

Standard air box with bigger intake tube is probably just as good, but you pays your money, you takes your choice.

But I have to say AMD appear to change more mafs than anyone else. And ed hasn't got a standard air box on his motor, as last time I saw his car, there was no motor in it.

I'm starting to think twice about taking it off, you all soon pretty positive about them!

My air-filter definately is filthy, possibly this is because I have cut the backs of the grill in front of the filter, has anyone else done this?

If not, how is the filter meant to get lots of fresh air?

I have heard the rumours that actually the MAF's are not actually bothered about aftermarket airfilters, but why are AMD so certain about me taking it off?

(If I do keep it on, I have a K&N cleaning kit I can give it a clean with.)

Mark.

Don't ever bother cleaning an oiled filter. A new one is ?30. I've cut the grille out in mine and had no probs. I'm on my third filter recently at 60K.

Jettex do a larger one that fits the carbonio, and i've had no probs with them.

Amd believe certain things, and I'm not saying that they're wrong, but it doesn't mean that they're right.

Ring jetex and ask them to send you the one Jabba use on their induction kits. Fits perfect.

Mine gets dirty over time, but not excessively

AmD have their opinion obviously, but they are by no means the only informed experienced company. Maybe more MAF's get swapped there for other reasons... who knows. (if thats even true)

If you do want to clean/reoil your filter, do so spareingly.. Re-oil it lightly, allow it to be absorbed into the filter, then blot out excess in kitchen towel. - thats my advise anyhow.

Alternatively, a regular cone filter from anyone should'nt cost the earth as a replacement new unit, so if you have some dimensions of the tube OD, and available size for filter, I could match up a Green cone filter to suit. I have seen protective outer "macs" that have been used on these remote filter induction kits, which are an easily washable thing, and catch the worst of the dirt, keeping it off the filter element. You are asking for a lot of filtration to be done with it in that location tho.

I am not a fan of placing an airfilter in a position where it can clog (loose airflow) easily from road dirt/water etc. You want good airflow and decent sized cold air feed pipe, somewhere where it can breath the air, but that does'nt mean the filter has to sit there.

regards

hi wilko, noticed your conversation about a new air filter, i have been offered a carbonio intake pipe but no filter, and from looking around realised you cant buy a carboinio replacement filter alone very easily, or can you? but if i buy one from jetex as you were saying it should all work ok??
