Recommended Spark Plugs

Was looking to change the factory spark plugs. Was wondering which plugs to use? I have full exhaust, Soon to have GT350 IM and Lund FF tune with 47lb injectors.

Stock OEM plugs are fine.

Stock plugs are indeed fine but if you have 80 bucks and no where to put it, get a step colder brisk silvers.

I went with stock temperature NGK 6509 Iridium IX for my 5.0.

Here is a nice chart to help you with your install, be sure to use an iridium friendly gapper tool. You don't want anything pushing up against the iridium tip.
