NGK V-Power Spark Plug BPR6EY (6 Pack) for ASTON MARTIN DB4 ZAGATO 1960-1963 3.7L/3670cc

NGK V-Power spark plugs offer economical performance for nearly any automotive application-and they're the only plugs with NGK's V-Groove technology. These plugs enhance ignitability, lower the voltage requirements of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs are also highly durable against electrical and chemical wear, making them long-life replacement plugs. Because of the V-Groove, the spark occurs at the edge of the center electrode-so heat is not absorbed by the electrode itself. This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance. Shorty Spark Plug: No. Resistor: Yes. Manufacturer Heat Range: 6.
