In a hurry.....Check this info..........
....I posted the following in another thread:
I'd have to conduct quite scientific tests to tell you what any improvements are, and you know what the placebo effects are!
My Carbonio intake came with a PiperCross panel filter and someone I know with a Mk5 GTI, who is a highly qualified engineer and whose opinion I respect, told me ITG were the best. The ITG filter is certainly of very robust multilayered construction and fits the 'box' very tightly, so sealing is good - Better quality than the PiperCross which in turn is much better than the standard 'paper' panel. Extremely low maintenance was also a factor in my decision - No additional oiling is ever needed and just an occasional dust off. Also a lifetime warranty.
Don't forget that the VW standard filter gets thrown away and replaced every ?,000 miles when servicing - What does that tell you?
The ITG Pro-filter utilizes the same three layer reticulated polyester foam used on the MAXOGEN air filters. Unlike some of the competition, ITG filters have a massive dust load-up tolerance, which is the ability to absorb a large amount of dust without reducing air flow capacity. With the standard K03 turbo I wouldn't like to say that any performance gains are appreciable without proper scientific testing. However, the manufacturers claim about +2 bhp is possible.
It's also MAF-friendly! And probably more benefit to a remapped car.
If you plan on keeping your car, as I do, then it'll quickly pay for itself by not needing to replace it - 60 squid well spent imo.
