NGK SPARK PLUG R5671A-10 ” 5820 “

Description

NGK’s V-grooved center
electrode moves the spark to
the outer edge of the
electrode for improved
ignitability in all combustion
chamber conditions. This
configuration is especially
helpful for throttle
responsiveness, quicker corner
exits, and more power on the
bottom end in a drag race
engine.

NGK V-Power
Racing Spark Plugs are
available in a wide variety of
heat ranges to fit most drag
race, circle track or road
racing applications. The
high-purity alumina silicates
used in the insulators of NGK
Spark Plugs helps keep the
spark plug tip warm enough to
burn off deposits at
low-speed, yet still be able
to transfer enough heat during
high-speed operation to
prevent detonation and
pre-ignition
