Spark plugs.

Why would you set the gap at 1.3mm?

Sorry 1.1mm that what was in the book when I first bought them and put them in the V6 plus I tested them with a feeler gauge.
Stock plugs are 1.5mm gap.

Just to avoid confusion, since the posts have not made reference to the fact that they are making V6 recommendations, V8 standard Commodore plugs are NGK BPR6EF (V-groove) plugs gapped to 1.0mm.
