Has anybody used a extended tip spark plug (on left, compared to normal)
on a later 22re engine?
On my plymouth w/slant 6 the engine runs smoother. The theory being that the spark is moved closer to the center of the combustion chamber. (slant 6 stock plug is 2 steps hotter than the 22re stock plug, but otherwise is the same)
They'll screwin, but I don't know if the piston top or valves will hit the extended tip.
