It will increase combustion temp. obviously, but it does decrease intake manifold temparature, which in turn will decrease the risk of detonation. At the 5OH shootout last summer with Adam's car it was 30*C. The car idled for 10 min. and then made a NOS pass down the track. The intake was sub zero (frosted) when he returned to the pits. It was freezing cold to the touch. I think that it does have some cooling atributes. I understand that just because the intake is cold does not mean the engine is cold, but it does reduce detonation. No?
