Brand: Champion Spark Plugs

This is the standard spark plug for Formula Ford 1600 (Ford Kent & "Uprated") engines running the original iron cylinder head.

Champion Spark Plug N6YC
ThreadReachHexTipHeat Range
14 x 1.25mm0.750"13/16" *ProjectedHot
* This hex is extremely tight in the SCCA aluminum head.
We also offer the Champion RC9YC plugs, which have
a smaller 3/4" hex.

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 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.
