yorgog Posted August 9, 2004 Report Share Posted August 9, 2004 Does anyone know the part number for the Irridium IX plugs for an 04 Tahoe Z71 with a 5.3 liter engine. I would like to get better plugs and wires. Also what is the gapping. I want the Irridium IX plugs. I have them in my 03 SS and I love them with the magnacore wires.
