The Iridium TT spark plug features the world’s smallest diameter centre electrode (0.4mm) and combines it with a needle-like, 0.7mm platinum ground electrode.
This allows the unique plug to improve performance, efficiency and durability – the Iridium TT represents an increase in performance and durability on standard iridium plugs and has a lifetime of up to 120,000km, more than three times that of standard nickel plugs.
Available for cars compliant with EU5/EU6, the new and improved plug offers advanced ignitability, resulting in optimum vehicle performance and efficiency.
The twin-tip electrodes allow for omni-directional ignition which, in turn, promotes improved combustion and allows the plug to burn fuel more efficiently. This improved ability of the air and fuel mix to ignite allows the spark to expand more quickly, which optimises fuel economy and performance.
DENSO’s patented twin-tip technology was previously only available on luxury or prestige vehicles but the Iridium TT now makes it available to all.
The Iridium TT features the highest concentration of iridium of any plug on the market – iridium is super-hard, very dense and is the most corrosion-resistant metal, meaning it can withstand extremely high temperatures.
The new spark plug was launched in Europe with a series of events designed to promote the brand to new audiences, connect with existing distributors and achieve press coverage. DENSO asked two racing drivers, Rebecca Jackson and Natalia Freidina to go head-to-head in a DENSO-branded Lotus Exige S at race tracks around Europe.
This was a fantastic way to build on existing distributor relationships as well as reach new audiences through the two drivers and their contacts.
