The Ultimate Spark Plug Thread - 04/06/10 02:56 AM

After looking around at different spark plugs for various applications (big and small block, aluminum and iron heads, etc) I thought it would be nice to construct a thread for the archives that catalogs various plug numbers and manufacturers.

For instance:

RB with 915's and headers:

Accel 8197 (set of 8)

Please add to this thread if you have any useful info.
