Does anyone know the gap setting measurement to set for new spark plugs to be installed on a 2001 S60? Thanks

 

Check under the hood. There should be a sticker regarding emissions controls which will also give you spark plug gap information. On my wife's, its located near the rear of the hood for some unexplained reason in a hard to read location. But it is there. Cars have had these for years now. Not sure if owner's manual provides this information (unlike, for instance, Honda) since the owner's manual thinks your mechanical ability pretty much stops at adding
windshield washer fluid and maybe motor oil.
