I know it's not a real performance mod, but does anyone have experience using these plugs, GM AC Delco 41-985, or GM Performance wires, part number 12495519. What do you use and do you like it? Thanks!
Duct tape and bailer twine!Oh yeah... and they couldn't stop the number 1 plug wire from falling off either....
I have the TR55IX part # 7164, Does that mean anything to you or anyone else?
How do you know what the gapping is ? I cant find it anywhere on the box
