NGK Resistor V-Power Spark Plug - ZR5F-11

NGK V-Power plugs feature a unique v-cut in the centre electrode that directs the spark to the edge of the electrode, helping the spark develop more rapidly, increasing ignitability and reducing quenching. NGK Resistor Spark Plugs incorporate an internal resistor to suppress ignition noise that is generated during sparking. Noise that is often referred to as either electromagnetic interference (EMI) or radio frequency interference (RFI) can disrupt electronic communication signals which effects the performance of sound systems, mobile phones, two-way radios and even engine management systems such as the ECU.

• Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
• Corrugated ribs prevent flashover
• Pure alumina silicate ceramic insulator, provides superior strength and better heat transfer
• Copper core aids in heat removal
• Triple seals prevent leakage
