Is it ok to use NKG platinum plusg on 1999 blazer 4.3l. Theu would not cause a misfire would they. Properly gapped.

NGK plugs are good plugs. I would go with the double platinum plugs for the longest life. If you go single platinum, the ground electrode is still nickle plated and will wear out faster than a DP plug.

I put the NGK Iridium plugs on my 97 and it did not like them one bit. I would have been better off to get the Champion copper plugs. Just my experience.
