Honda GX 690 Spark Plug: Plug #ZFR5F

NGK V-Power plugs feature a unique v-cut in the center electrode that directs the spark to the edge of the electrode, helping the spark develop more rapidly, increasing ignitability and reducing quenching.

• 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

Honda GX 390 Spark Plug: Plug #BPR6ES

NGK Standard spark plugs (in the iconic NGK 'yellow box' packaging) are a proven OE cornerstone and technology customers have relied on for decades. Engineered specifically for OE applications, NGK Standard spark plugs provide OE quality nickel alloy reliable performance and design. NGK's legendary high grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance, while triple gasket sealing prevents combustion gas leakage. Solid 98 percent pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges. Trivalent metal plating ensures superior anti-corrosion and anti-seizing properties

• ACTUAL OE or EQUIVALENT DESIGN: OEM quality construction nickel alloy center electrode provides consistent performance
• RECOMMENDED USAGE: Best for vehicles with OE nickel alloy plugs, not recommended on vehicles with factory precious metal plugs
• NGK's OE CERAMIC TECHNOLOGY: High grade alumina silicate ceramic creates a stronger insulator for optimal dielectric performance
• SOLID COPPER CORE: 98% pure copper core offers superior heat dissipation, conductivity and ultra wide heat ranges
• COLD-ROLLED THREADS: Prevents cross-threading and damage to cylinder heads
• TRIVALENT METAL PLATING: Delivers superior anti-corrosion and anti-seizing properties, ensuring ease of installation and removal
