CalVin Plug Gap?
« on: July 07, 2016, 04:43:42 PM »
What is the optimal spark plug gap for a 2008 Cal Vin?  Sorry if this is redundant.  Can't find the thread.

 .6-.7 mm  (.024"-.028") is the factory recommendation. I run mine at the top end of that spec with good results. That's the outer plugs...no spec given for the inners but they are a special construction plug and gap isn't supposed to be adjustable.

It's good I asked.  One of the plugs was .1 mm off target.  Thanks again, Terry.
