Spark plugs 3.8V6
I want to replace the original platinum sparkplugs AC Delco 41-921 from my 3.8V6 Camaro (2001).
There are several topics about this issue, what is the best replacement:
AC Delco 41-101 or NGK PTR4B or NGK TR55IX
and should the gap be the same as original ?

You know what, you're right! I have an old set of originals laying around checked the numbers and sure enough the numbers match the ones you posted.. My new ones are the 41-101's.. I can tell you though @ 80+k my old ones still look like yours. Good plug too in my book..
