    It's a good plug

    I use these on my bike I have never had a problem with a plug failing it is my second set last time they changed was 3 years ago and and they were working fine when I pulled them so all-in-all I think it's a great plug

    Runs good

    Replaced my standard NGK that suffered an early low end misfire issue. Replaced them with NGK IX and running well again. Would have been fine with the OE plugs as the cure, but will see if the IX give better life...
