IRIDIUM TT

IRIDIUM TT spark plugs feature a unique twin-tip design combining a 0.4 mm ultra-fine iridium centre electrode with a 0.7 mm needle-type platinum ground electrode. This advanced construction boosts horsepower and torque while delivering smooth and efficient engine performance at a competitive cost.

Structure & Technology

DENSO IRIDIUM TT spark plugs are engineered to reduce the quenching effect by using a double needle electrode design. This allows faster flame kernel development, enabling the engine to reach its full performance potential.

• Built-in Highly Reliable Resistor
  All types include a monolithic resistor to eliminate electromagnetic interference with electronic devices.
• 360° Laser Welding
  The iridium tip is mounted using an all-around laser welding process, ensuring high durability and reliability even under extreme conditions.
• 0.7 mm Needle-Shaped Platinum Ground Electrode
  A fine platinum ground electrode minimizes quenching while maintaining strength and wear resistance thanks to advanced laser welding technology.
• 0.4 mm Ultra-fine Iridium Centre Electrode
  DENSO’s exclusive iridium alloy allows for an extremely fine electrode tip, reducing required ignition voltage and significantly improving ignitability.

Performance Advantages

Improved Flame Growth
Compared to conventional iridium spark plugs, IRIDIUM TT maintains strong flame development even with a reduced spark gap. This results in better combustion efficiency and higher engine performance.

Lower Voltage Requirement
The fine electrode design concentrates the electric field, allowing ignition at lower voltage levels while maintaining strong spark performance.

Higher Ignitability
Testing shows improved ignitability, leading to higher idle stability, smoother operation, and better throttle response.

Better Fuel Efficiency
Reduced combustion variation improves efficiency. Tests show up to approximately 3.1% reduction in combustion fluctuation and around 2.4% lower fuel consumption compared to standard iridium spark plugs.

Key Benefits

• Increased power and torque
• Faster throttle response and smoother acceleration
• Improved fuel efficiency
• Lower ignition voltage requirement
