I have a 2001 Chevy Xtreme with the 4.3L V-6. I am going to be installing a 6AL ignition with an MSD coil (part no. 8231) and would like your suggestion on plug gap and heat range. The factory gap is.060. I don't know the heat range. The truck also has a Flowmaster dual outlet muffler; Airaid intake; Hypertech power programmer 3 set for 93 octane tuning if any of that will make a differance. Thanks!

With the MSD unit installed you should not need to change heat range on the plug, and the gap that the plug currently has will be fine. Just stick to a standard plug and you should be fine.
