Brand: Champion Spark Plugs

Champion Spark Plug C61YC
C Series, 14mm thread, .750" thread
5/8" hex, Projected Tip, Warm.

The projected gap style positions the spark an additional 1/8 inch into the chamber and, providing there is sufficient clearance to valves and piston, provides the ultimate in performance. Initiating the flame front closer to the piston top at a given spark timing has the same effect as advancing the ignition timing. Therefore, maximum timing may be reduced, which helps to reduce detonation and octane requirement while still providing good part throttle response. For normally aspirated engines only; not recommended for turbocharged, supercharged, nitrous oxide or nitro burners.

Replaces discontinued Champion plug FN507Y.

I know these plugs ; recommended by Peter Molloy, the ace engine builder of the competition Climax FWE. They work exceptionally well. Price, and the usual great service from Pegasus clinched the deal.
Thanks Pegasus,
