Pretty cold, compare them on the Autolite spark plug conversion site Or go to Champions site for there heat range chart The N57 is a retracted gap, the 3910 is a projected gap, if your ignition is marginal use the retracted gap plugs, regardless of brand or heat range Last edited by Cab_Burge; 10/15/12 01:07 PM.
