So you believe the stock air box is cold as ice and has little heat sink, just advance timing to reduce knock and forget CAI config with AFM because factory is best ?

Did I really say that? I don't think so.
I was saying that a cone filter won't make a difference knock-wise with the airbox/snorkel with chips such as the "Cup 290bhp" which, unless you know already, feature a very agressive timing curve in higher RPM compared to stock or even aftermarkets such as Guru/MaxHP (etc).

...and you wouldn't get any more knock running the stock airbox/snorkel.
The original "290bhp" Cup fuel/timing mapping done by Snobeck for the 1990 Cup series in France are knock-safe, even in very hot weather, but that is when running a stock K26/8 turbo, not some Garrett/KKK hybrid with, I assume, a different compressor map, which seems to be your case.
