Denso Iridium Spark Plug — IT16TT
The Denso IT16TT is an iridium spark plug using an ultra-fine iridium centre electrode for superior ignitability, sharp throttle response and a long service life.
- Ultra-Fine Iridium Centre Electrode: concentrates the spark for easier, more complete combustion — delivering high ignitability and sharp throttle response
- Long Service Life: iridium is far harder-wearing than standard or platinum electrodes, extending the interval between changes
- Superior Anti-Fouling: resists fouling and maintains a stable idle across a wide range of operating conditions
- Performance Upgrade or Premium Replacement: an ideal choice for modern and performance engines wanting reliable ignition and smooth running
- Denso — Pioneer of Iridium Technology: Denso developed iridium spark plug technology and is known for producing some of the finest centre electrodes available
