Sorry for bringing an old thread back to the top but I replaced the plugs with the standard factory Delcos and my 4.3 loves em. I noticed a decent difference, but that's probably because a couple of my old plugs had crud built up on them from age and possibly some light oil burning.

My 2001 has original plugs at 165K miles. Will I have problems getting them out?

When i search for AC delco plugs to my 1997 Blazer 4.3 Vortec, 41-913 platinum plugs are recommended. Could i still use CR43TS to save a little money?
If i search for plugs for the same car but 1995 model CR43TS are recommended. Is there something changed in the engine configuration between 95 & 97?
Thanks,
