NGK BR7ES Equivalent. DENSO's patented U-Groove spark plug enables complete combustion by allowing the spark to fill the gap created by the U shape. The ball of fire created in the U-Groove develops a larger and hotter flash front that virtually eliminates excessive fouling and erratic starts caused by poor fuel mixtures.

100% PRE-FIRED — Assures the highest quality possible.
COPPER-GLASS SEAL — Bonds the center electrode and insulator together for a gas-tight seal. Maintains proper heat and excludes hot combustion gases.
FIVE-RIB DESIGN — Prevents flashover and decreases voltage loss.
PURIFIED ALUMINA POWDER INSULATOR — Provides exceptional dielectric strength and thermal conductivity allowing the material to stand up to extreme stress.
