You mean the spark plug gap? It is listed on a placard under the hood and in your owner's manual. You did not list engine size so I cannot tell you.
.60
That is the rubber boot that is on the end of the spark plug wire that goes onto the spark plug.
A person must leave the right size gap for the spark plugs when changing them. The 1999 Chevy Suburban has a spark plug gap of .060 inches.
.060 of an inch
.060 Inch
0.060 inches
The spark plug locations are all on the same side of the engine. They are in the side of the head, where the plug wires are connected.
The spark plug gap in your 1999 Chevrolet suburban is dependent upon the type of engine. The standard engine spark plug gap is .011.
