I have the Bosch +4 (4418) in the dak right now.
These plugs are the stock heat range so if I run into any hint of
detonation I'll switch to the 3923's
On the stock RC12 Champions I noticed first that the coloration was
consistent. Reddish brown and speckled on one side of the insulator and
burnt on the other.
The electrode was worn at an angle towards the burned side of the
insulator. I thought the erosion of the tip was pretty excessive for
11,000 miles. I also thought it was strange how the wear was on the side.
One side of the plug must be seriously shrouded.
