Spark Plugs (Autolite) (set of 4)
These Autolite plugs are a suitable alternative to Champion RJ12C plugs, and are preferred by many of our Atomic 4 customers.  Like Champion RJ12Cs, they have a heat range slightly above Champion J8s which Universal used on their Atomic 4s throughout the 1970s. Like their Champion counterparts, these Autolites give slightly better performance, particularly in older engines that tend to foul plugs more quickly.
