Default Low Boost Turbo - What Spark Plugs
Installing a 7875 turbo on a 2000 5.3... planning on very low boost initially, maybe 5-7 PSI... will I need to change the heat range of my plugs?

this is what I would go ahead and run too! And the number for them are NGK 3346, that’s what you ask for when you go in a parts store.

Tr6s would be fine for low boost but would do the 7s higher then that. They both idle just fine. 7s just give you that extra cushion if you happen to over boost for whatever reason.
