Platinum Spark Plugs

People.

What should be the correct spark bridge separation for autolite platinum-pro spark plugs, in order to get a better performance? In other words, I just bought them and need to set the right calibration value before install them on my sweetie. ;)

Thanks everybody,

MC

39 is what my book says
they are probably set from the factory but check them all the same.

be carefull checking them, you can scrape the platinum coating off
