Brand New OE Spark Plugs with some seriously different spark gaps... 043 is the targeted gap but that's not what I had for all 6 plugs. Tightest gap was .006 😬

This is a good example why you should ALWAYS check any new spark plugs prior to installing them.

These would have been installed under an intake manifold plenum which is a 2.6 hour job to do.
Sure would suck to do this job twice for a one time pay. 😜😤
