To settle a "discussion"... Is there a Cup rule about air cleaners? If so could someone print it for the "discussioners"? Please..

Found this
NASCAR (stock-car and truck) racers have a choice of K&N’s new replacement air filters (E-3024R, E-3025R, E-3026R, E-3027R, E-3028R, E-3029R, E-3030R, E-3031R). “The 14 inch round filters are for the NASCAR Craftsman Truck Series and the NASCAR Busch Series; The16 inch round is for the NASCAR Nextel Cup Series,” said K&N Engineering Sports Marketing Director Charles Maier. “We offer the new filter to teams in quarter inch increments from 3, 3 ¼, 3 ½, 3 ¾, and 4 for both the 14 and 16 inch filter.” There are 5 of the size 14 and 5 of the size 16. Eight filters are available now and two more will be available soon.

NASCAR rules require air filters in order to race. K&N’s new 2-ply cotton un-oiled filters meet NASCAR requirements. “The 2-ply cotton works the same as our 4-ply,” said Maier. “It just allows more air to flow.”
