I had an ITG kit in my last GPX and it was 6 years old by the time I sold the car to Adrian no. 1 - the filter held up without any sign of deterioration over that term. I assume the same filter in in Adrian no.2's car and is still going strong!
Note that ITG filters came out on top in an FTOOC test a few years ago beating all others (including K&N) in terms of performance increase.
The great thing about ITG filters is that you can wash them in a bucket of suds - not an option with some K&Ns and equivalent.
