    E3.31 is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from tried the plug I am using it in a snowmobile and saw no change in performance, it will be hard to know if all the claims are true because of how mountain snowmobiles are run. as long as it fires, no hiccups throughout the power band I am happy.
