Spark Plugs.

[speedkills]

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

Regarding spark plugs, what has the industry learned for spark plugs for a non nitrous engine?

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

Iridiums it is. Thanks for the info.

What Gap do you set them at I have heard anywhere from 40 to 60. NGK web says 40, GM says 60????
