  • I'd stick with OEM which should be AC Delco. Do you have the owners manual? It should list the exact plug.
  • OEM spark plug wires are known to fail. The best ones out there, that most people have already changed to, are the blue Silicone wires with the heat shields made by Taylor Extreme. Shop around for the best price. Taylor Extreme
  • If you haven't changed anything else why would you go other than OEM?
  • In my world there are a few things where you don't stray from oem without a good reason... Ignition parts are top of the list.
