Elevate your engine’s ignition with Denso IKH16TT Iridium TT Spark Plugs

Engineered with iridium and platinum technology and a 360-degree laser weld, these plugs are designed to offer long service life—often exceeding 100,000 miles under routine driving conditions. The Twin-Tip design concentrates spark energy to promote confident ignition and smooth running across various RPMs.

What sets IKH16TT apart is the combination of ultra-small tips and a robust alloy that’s engineered for durability. The world’s smallest 0.4mm iridium center electrode paired with a 0.7mm ground electrode reduces spark interference and could contribute to better power, torque, and fuel economy in practical driving scenarios.

Key benefits at a glance

  • Twin-Tip technology focuses ignition energy for crisp throttle response and steady acceleration.
  • Iridium TT design supports consistent ignition in high-demand conditions.
  • Durable construction aims for extended service life and fewer replacements.

Real-world use cases

In daily commuting, the plugs may help maintain steady idle and smooth take-offs. On highways, they can support efficient power delivery and better throttle feel. Enthusiasts may notice more confident cold starts and consistent performance across seasons.

Installation-friendly features

  • Machine-rolled threads prevent seizing or cross-threading during installation and removal.
  • 100% pre-fired to assure the highest quality possible.
  • Purified alumina powder insulator provides exceptional strength and thermal conductivity.
  • Five rib insulator prevents flashover in challenging ignition scenarios.
  • Copper-glass seal bonds center electrode and insulator for a gas-tight seal.

FAQ
