The Platinum TTŪ concept originated from DENSO's latest original equipment spark plug technology, the Super Ignition Plug (SIP). Until recently, this OE iridium Twin-Tip design could only be found in the most technologically advanced automobiles. But now DENSO is offering this cutting-edge technology in a brand new platinum/titanium design customized for today's value-minded automotive enthusiasts. The additional tip of the ground electrode results in less obstruction of the spark growth, while still maintaining the same gap. Less interference at the spark origin (quenching) means better ignitability for a more powerful and fuel-efficient combustion.

Features:
  • 1.1mm platinum center electrode
  • Titanium-enhanced alloy ground electrode
  • Minimum-quench electrode design
Benefits:
  • Improved fuel economy
  • Faster starts
  • Enhanced flame propagation for increased engine efficiency
  • Free standing firing pad reduces quenching to generate a more powerful spark
