Denso TT Platinum Spark Plug 4506

Twin-tip design enables faster flame propagation for more complete combustion.

• 
  Twin-tip technology with 11 mm platinum center electrode and 11 mm titanium enhanced ground electrode
• 
  Improve fuel economy, better acceleration and faster starts than all other single platinum plugs
• 
  Purified alumina powder insulator provides exceptional dielectric strength and thermal conductivity, allowing the material to stand up to extreme stress
• 
  Copper-glass seal bonds the center electrode and insulator together for a gas-tight seal; maintains proper heat and excludes hot combustion gases
