Chevy Trailblazer spark plug replacement 4.2 I6
A how-to video for replacing the spark plugs in a Chevy 4.2 I6 engine.
Always use AC Delco 41-103s in this engine.
NOTE: The AC Delco 41-103s are pregapped from the factory. That's why they
have the plastic sleeve things in the box, so the gap won't change during
shipping and handling. For what it's worth, I have replaced hundreds of the
delco iridium plugs and haven't gapped a single one. If for peace of mind
or whatever you do decide to gap them, do not use the "silver dollar" gap
tool (or equivalent).
