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 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.
