TOYOTA GAZOO Racing start the 2019-2020 FIA World Endurance Championship season in style
It's what's inside that counts
Introducing the Iridium TT Spark Plug - featuring, at 0.4mm, the world’s smallest diameter centre electrode and a 0.7mm ground electrode. This aftermarket range makes advanced OE-quality technology available to a wider range of vehicles at an affordable cost. It offers 3 times the lifetime of a Nickel plug and delivers better fuel economy and all-round optimum vehicle performance.
Nickel Plugs feature two flat surfaces, which block the ability of the ignition spark to grow. But DENSO’s Iridium TT’s two needle-thin electrodes (with the center electrode 0.2mm smaller than the nearest rival) 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 quicker and better, 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.
The complete Iridium TT Spark Plug range is highly consolidated and caters for the majority of the top selling EU car park.
