I think it's .06 but if you get Bosch Platinum plugs, you won't have to worry about it.
1 plug per cylinder so 6
A 6-cylinder has SIX and a 4-cylinder has FOUR spark plugs.... Am I missing something here?
It's a royal pain... The back plugs are the hardest to get at if you have a 6-cylinder engine. It's not impossible but you might have to rely on sense of feel. (Who designs these things anyway?)
Just follow the spark plug wires....
Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another. Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings

.060 is the typical spark plug gap for your engine.
Under the engine cover is the coil pack housing. Remove the engine cover to reveal the coil housing; this unit attaches to your spark plugs through the spark plug boots and retainers. Inside the housing are your two coils.
.060 (Double-check with a Buick dealer's service center. They'll know for sure).
There would be six spark plugs for a six cylinder engine. One for each cylinder. Unless it is a diesel, then there are no spark plugs.
It's near the top of the engine, close to the rear spark plug wires. It's round and either brass or a dark gray color. You can't miss it.
Count the number of spark plug wires. There is one for each cylinder.
