Louis,

You can get the OEM sparkplugs from Ecklers. They are ACDeclo plugs. The Ecklers part number for the LT-4 is 32663.

When I did the plugs and wires in my GS I used the ACDelco plugs and the Spiro-Pro plug wires from the Ecklers catalog. they are 69.99 for a set, and I've been pretty happy with them so far.

Jason,
Thanks for the information, does this plug have the platt that either burms off or falls off?? As I am NOT using a duel platium style plug this time. I have read on the Corvette Forum that several other brands of this type of plugs have the same problem.I pulled all of the plugs and 5 out of 8 were missing the platt (disc) on the ground where you gap the plug at. I hope they did not scratch the cylinder wall.
Thanks,Louis
