Denso Spark Plug

Denso's Premium Class Double Platinum Spark Plugs provides the most durable and reliable performance by incorporating the latest and most reliable design and materials for a spark plug.

Features:

  • Designed with heavy duty insulator that provides unparalleled dielectric strength and thermal conductivity under extreme temperatures
  • Five-rib design prevents flashover while decreasing voltage loss
  • Copper glass seal bonds the center electrode and insulator together for a gas-tight seal
  • Platinum center electrode utilizes platinum to shrink the surface area of the center electrode tip for maximum firing performance and minimum voltage requirements

Customer Review: (see review/s)
  • Due to the age of the car and the high heat that a engine puts out sometimes ignition coils get cracked and brittle and I would recommend changing at the same time. It is a pretty easy fix and would boost your engine mileage as well
