Spark plug questions: 2004 6.0

[BigClay]

Are NGK and AC Delco the front runners in plugs for the 6.0 in my Denali? Also what mm wires are you guys running? I am new to this engine, so how hard is it to replace the plugs? In my Tahoe it was extremely easy to get to all the plugs, hoping this one is as well.

I just run AC Delco plugs and wires, no need for aftermarket wires unless you have some real mods done.

i have delco plugs and wires as well, but i believe the oem spark plugs are ngk

When I pulled the plugs out of my 04 they were NGK but the new one's I put in were AC Delco platinum.

I also ditched the stock wires for a set of MSD 8mm you can pick up a set of those for $50 -$70 with a set of NGK plugs if you look in the right spot.

Where's the "right spot" for the MSD?
