I enjoyed the thread on the spark plug wires. Wonder who makes the plug wires for Granatelli?

And fu..... ebay.

For cars not running nitrous, NGK or AC Delco Iridiums are the way to go. They are actually the same plug, NGK makes them for AC Delco, so its just a matter of brand preference or what you can find.
They are about $7 a plug, but they will give you great spark, the least gap erosion, and the longest life. Change them once and forget about it
