Spark Plug Heat Ranges & Applications

AR473 - Autolite Race Series Spark Plugs is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from no more autolites Have been running auto lite ar 473's in my v6 drag race engine for nearly 10 years now. After the issues I had this spring I'll have to run NGk plugs now. Bought 2 sets of ar 473's for my fresh engine, spends 3 days trying to figure out why it would only run on about 3 cylinders. After trying everything I could think of any wasting a day at the track in desperation I put a used set of plugs from last year in the engine.... Ran perfectly. Live and learn .
