Iridium TT technical details
Standard Nickel Plugs feature two flat surfaces, which block the ability of the ignition spark to grow, but DENSO Iridium TT has two needle-thin electrodes (with 0.4mm Iridium alloy centre electrode and 0.7mm platinum ground electrode) these act as thinner ‘fingers’, allowing the spark to grow 360 degrees in all 3 dimensions.
This improves the ability of the air and fuel mix to ignite and, in turn, allows the spark to expand faster and more strongly, optimising both fuel economy and performance.
DENSO’s cutting-edge technology has created a unique iridium rhodium alloy with the highest iridium ratio in the market for the center electrode as well as a bespoke platinum alloy for the ground electrode, allowing for the extended lifespan of the plug.
- Vastly increased endurance - Life span of up to 120,000 km.
- Improved Ignitability - Stronger spark delivers better ignition performance.
- Improved Output - Low voltage requirement and high ignitability improves combustion.
- Reduced Emissions - Improved ignitability leads to less combustion fluctuation, resulting in less fuel consumption and significantly reduced CO, CO2 and HC emissions.
- Technologically Advanced - Delivers all-round optimum vehicle performance to a much wider range of OE vehicles at an affordable price.
