Getting ready to do a tune up. I see that our plugs factory are iridium correct? So I was wondering if I should stick with iridium or could I go with platinum? Also if I stick with iriduim what plug does everyone recommend? I only ask about the platinums, because I ran the Bosch platinums in my 90 5.7 and had pretty good luck.
Thanks in advance.
Stock AC Delco's
Different plugs won't do a thing.
But another brand will not hurt anytting either correct?
NGK Tr5's
i use ngk tr55ix or if not, just the plain tr55
NGK TR55's here. I've heard bad things about Bosch and E3.
Platinum is a downgrade. E3 is junk, i dont put bosch stuff in my truck.
NGK, ac delco, denso, whichever is cheaper.
Looks like it will be NGK or AC Delco then. I gotta do some price checking to see who has the better deal. The 100,000 mile tune up is coming up real soon. The 1st complete tune up that is.

What is the difference in the tr55 and the tr55ix?
