    I checked our forum's research area but could not find this information. Does anyone know of a web site that provides a chart showing spark plug equivalency. For example, I would like to know the AC plug equivalent for the Champion J12YC plug? Is it AC44 or maybe AC45? Thank you.

    I just look in my old AC Spark Plug catalog.

    sometimes I look up plug numbers for a vehicle application on a parts web site, like rock auto. It is not always right, though.

    No need to replicate what's already within the internet.
    You just need to...Google it !

    Thank you all for commenting. As Mike VV mentioned, I found charts and answer via google.
