plugs

[Belsy]

What is the concensus on best all around plug choice for a '95 ?? I have always liked Bosch but they only show 1 for '95 yet 5 choices for 92 and older. Any thoughts?? Are the plug size & thread the same for all? Anyone tried Denso?? They seem popular.
Any opinions appreciated,
Thanks

My 91 originally came with FR2LS (or something similar). This was superceded by platinum tip later (I think).
I tried AC Delco platinum back in 2002 and later found out insulation had cracked on one of the plugs and that's why the car was missing - trashed them.
I ran AC Delco Rapid fire for a while (7 years) but switched to Denso Iridium recently. Both run fine in LT5.

the 90 gap is 35 i believe , what year did they change it to 50 . i run mine at 40. the plugs for the 93 that wasnt a gasket plug came from ngk @50. i wonder if there are any changes to the electronics when they upped the gap????????????
