Fitment
These G-Power Platinum spark plugs deliver the power and quality that you expect from NGK. The fine pure-platinum electrode tip remains virtually unchanged and reaches self-cleaning temperatures to deliver longer durability and optimum performance. Compared to conventional plugs, G-Power plugs deliver better starts, superior acceleration, and greater fuel economy.
- Fine wire platinum tipped center electrode reduces required voltage for better starts, superior acceleration and increased fuel economy
- Trapezoid cut ground electrode reduces 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
- MPN: GR4GP
