I just replaced mine with NGK PFR5G-11. The Infiniti manual says that is the standard, the NGK PFR6G-11 the manual says is the cold type. These are the double tipped platinum laser welded plugs.

Its just one of those things. For whatever reason NGK's work the best on J30's/300ZX's.

Their are literally hundreds of threads on this forum and others about bad results with non NGK plugs.
