What Spark Plugs Are You Using?

[racertb]

Greetings:

Just an informal poll of what spark plugs you are using in your Plymouth's...feel free to state why you like what you're using over another brand/type you may have tried.

I'm currently running AC Delco C87's, but have long used Champion D16's.  Not sure if there is really any difference at all.

Hi Ted,

I've been using the Champion D16 or their equivalent for many years in my '29.  Put new in this summer and believe they are now called 516.  Seems to start, run ok, but have nothing to compare.

I am also using the AC C87.  I like using AC since the original plugs were AC.  The AC C87 is a hotter plug than the Champion D16 (which I used for years) and I think it reduces fouling and runs a little better.  Our cars came originally with AC G12 plugs, but the G14 plugs were also used for the same reason, they are a hotter plug that tends to reduce fouling. I have a set of original AC G14 plugs but have been waiting to use them.
