Brand: Champion Spark Plugs

Champion Spark Plug RN4YC
N Series, 14mm thread, .750" reach
13/16" (21mm) hex. Projected Tip, Hot.

The Projected Tip 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 advance has the same effect as advancing the 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, nitrous oxide or nitro burners.

Replaces discontinued Champion N4YC plug.
