What is the correct spark plug gap, for a 2001 Grand Prix GT with the 3.8 Liter engine??

Please advise.

Thanks!!!
 


Welcome Canuck
Not sure if this is all general spark plugs but if your using Autolite 605's: 3.8” factory pulley: .055-.057” gap

havent heard good things about bosch plugs but i have heard good things about the brisk silver plugs.

If you were interested in them, shimmy over on OQCGP can get some for you.
