Hey guys I run the Autolite 45 , and I would like a colder plug at least on heat range does anybody know a good plug and part number? Cheap ones tho please cause this is just my race car and it goes thru them fairly quickly.

Thanks

with autolite you just drop a number to go down a range, 44 is one step colder than 45.
