Product Details

The NGK 3716 (TR5-1GP) G-Power Platinum spark plug gives you the durability of platinum at a competitive price. It has a fine wire platinum center electrode and a trapezoidal cut ground electrode. Together they help deliver quicker starts, better acceleration and improved fuel efficiency over conventional nickel spark plugs. It is a good upgrade for engines that came with nickel alloy plugs from the factory.

Key Features:

  • Single platinum tip: 0.6mm fine wire platinum center electrode for durability and a stable spark
  • Trapezoidal cut ground electrode: reduces quenching for better ignitability and performance
  • Solid copper core: improves heat dissipation and conductivity
  • Trivalent metal plating: resists corrosion and seizing
  • Corrugated ceramic insulator ribs: help prevent flashover
  • Triple seals: prevent leakage
  • Resistor design: 5k ohm resistor for radio frequency interference suppression
