Hi Guys,

Does anyone know what type the heads are on the V10 ? Aluminum or Steel?

I need to do a spark plug change this weekend (truck idling kind of rough) and going to go with the Champion Truck Plugs.
I heard that you need to put antiseize on the threads of the plugs if the heads are aluminum, but I am thinking it might be a good idea to put it in either way.

The truck is going on 50K miles the dealer did the first change at 36K I believe.

Any thoughts would be greatly appreciated.

Thx
