I bought the ITG, but found it way too oiley for my liking. There have been many disputes as to whether oiled filters are good for the MAF etc and I'm sure that the ITG product is very well researched and proven, but I just wasn't happy with the amount of oil that was on the filter - even after I had done the initial wipe down!
I now run with the Pipercross that came with my Carbonio.
Its up to you though mate.
