Spark Plugs----charts?
Has anyone run across a source to compare spark plugs from one maker to another, and heat ranges? I know some catalog books will have the charts for a particular OEM comparison, but I think we could use a general chart.

I'd suggest sticking with AC Delco on the plugs.... :thumbs:
The heat range is the 2nd number where R43 TS would be a 'cooler' plug compared to an R45 TS which is a 'hotter' plug.
Crossovers charts can be found at automotive stores (i.e. Autozone) - They can tell ya (it's the binder behind the counter) what Champion plug would substitue for an AC Delco R45 TS and so forth. ;)
Here's a link for AC Delco --> http://www.acdelco.com/html/pi_plugs_ident.htm
If I can find one for brand crossovers....I'll post it. In the meantime - good luck ! :thumbs:
