I have some plugs that I already purchased on Ebay. I sure would hate to waste them. I got this truck from my brother, a 1998 Chevy Silverado 1500 4.3L. He was the original owner. This is my first time tuning it up. I buy most of my stuff from Ebay. I bought a new AC Delco Cap and Rotor. I got a set of Napa plug wires for .99 + 6.95 shipping. Not bad, considering they are $32 at Napa. I am a Disabled Veteran, and I learned how to bargain shop a long time ago. Now, my question is.......I bought a set of spark plugs off of Ebay. According to Autozone it is one of the plugs on the list, that is used in my truck. I bought a set of 8, really cheap. I'm talking $10 cheap. that was price plus shipping. They are the plain copper plugs. AC Delco R44LTS6. The parts store says they will work. The one mechanic I spoke to says he didn't recommend them. He said it would affect my fuel mileage. Now, I am a mechanic by trade. I've got an associates degree in it, and I was a mechanic in the military. So, I have been around a little. Just don't have any experience with Chevrolet. All my time in the trade was spent with Chrysler. My experience says that all types of spark plugs conduct the same amount of electricity, but yet, I know that copper is the better conductor. Difference being, the longevity of the life of the plug. Unless somebody has better, more experienced info for me, I think the plain copper plugs would do fine. I'd just have to do a good old fashioned tune up, every 2 years. Like the days of old. If I am right, what do I gap them at? If I am wrong, what is the best economical, and still good performance plug? I did find a set of 8 AC DELCO IRIDIUM SPARK PLUGS; 41-993, for $24 + $5 sh. I know that is an excellent price, I just hate to waste the other copper plugs that I done bought.
