Time to change out the plugs and wires in my 04 6.0 Yukon, what are some suggestions for a good plug and wire to choose for a few planned mods like cam and headers and a tune, I also will be adding a electric fan as well should I add a lower degree thermostat?

 

MSD, Delco or NGK

 

NGK TR5's will work. OEM wires. Dont change thermostat

 

If the tune is going to add timing or your going to put no2, I would use NGKTR6IX plugs, MSD or Taylor wires.

 

How do I say this, ummm Stock and stock... Yah thats it

 

If anything it will be boosted later but not anytime soon and it will never see n20

 

For the record. A projected plug such as the tr6s are not recommended for nitrous. For nitrous use NGK br6ef
