I don't know if you'll find much data on this, as these types of tests would be performed by the folks trying to prove their products are superior.
I can provide you a datapoint. I recently encountered a K&N in a 5000 turbo quattro. It is incredible the amount of crap I found down stream of the air filter. I had to disassemble everything down to the turbo and flush all the oil coated crud out. This would not have been the case with a stock filter. If you consider sandblasting the impeller on the turbocharger as the hot tip, then go ahead and use the K&N.
[I have been informed that K&N filters are bad for my car. I would like to see
the data on this before I install this filter in my car. I will stay with
factory filters if the data indicates that K&N filters could allow damage. I had
never heard any of this before. If anyone could point me to any technical data
or past discussions where this is indicated, I will be open to learning about
it. If this is true that it causes damage to our Audis, then K&N needs to be
upfront about it, or at least hear from those whose cars have been damaged.
Anyone else have input on K&N? Thanks Greg
