There might be a small difference between the 0.9 gallons of fuel sloshing around in a half full YZ450 and the 9000+ gallons in a C-130 executing a 60 degree bank at low speed. Just guessing. But I do so enjoy the sarcasm. I tried my 06 with and without the foam. I couldn't tell a difference at all. My 08 has NO foam in it.
