It looks like the rule book reads differently than what the cooling police were enforcing. Note: the staging area is the staging lanes.

Under General Regulations Section 20 Page 5

Fuel/Air: Any method of artificially cooling or heating fuel prohibited (i.e., cool cans, Freon, wet rags, etc.), except as noted in Class Requirements. Cool cans, wet towels, etc. are permitted in Super Stock, Stock, Super Comp, Super Gas, Super Street, and E.T. classes. Wet towels, rags, ice, etc. must be removed before vehicle leaves staging area. Ambient-temperature air only; cooling or otherwise changing the conditions of the intake air is prohibited. Spraying of intake with any artificial spray or coolant prohibited.
