.060 inch (Use AC type 41-940 platinum plugs or equivalent)
I belive .060 of an inch is correct, but to double check. Thereis an emissions tag sticker located in the engine compartment. It will list the engine size, and year of the car. There will also be a listing for the, "gap." This will tell you the correct spark plug gap. Most cars have this sticker.
the spark gap for the 3.1 is 60,
What is the spark plug gap for a 2006 chevy malibu 3.5L v6
spark plug gap 2004 Chevy Malibu 3.5 litre
The plug gap is .60
It is .060...
O'Reily's says 0.52"
gap is 0.60,
if its a 3.1 its 0.60 thousandths
I have a 1998 Malibu and we gap at the middle of .060. Perhaps our cars are similar at this point, check!
