2004 Trailblazer 4.2 Spark Plug and coil Change - DIY in under an hour!

Today I do spark plugs and coil change on a 2004 Chevrolet Trailblazer with the 4.2 in line 6 motor. The job was done in under an hour and the only issue we had was that the new coils from amazon had a few bent prongs on the connector that needed straightened. Tools and parts info below. This is a great DIY job for anyone with basic tools and an hours time.

Tools :
8 MM or screw driver for clamps
10 MM for Coil Bolts
Spark Plug Socket
various extensions
Anti-Sieze
Dielectric Grease

Parts :
Spark Plugs - AC Delco 41-103
