DENSO Iridium TT Spark Plug - IT16TT

Please use our DENSO Spark Plug Lookup or contact us to find the right spark plug for your car

The design of the Denso Iridium TT plug means that less voltage is required to create the spark and less energy to make the connection between electrodes. DENSO’s cutting-edge technology has created a unique iridium rhodium alloy with the highest iridium ratio in the market for the centre electrode as well as a bespoke platinum alloy for the ground electrode. The resulting spark is more corrosive and allows an extended lifespan of the plug.

The Iridium TT plug better controls the vehicle’s engine, resulting in reduced misfiring and less fluctuation in the engine revs, particularly while idling.

Popular Applications: Ford Fiesta IV / Mondeo III, Mazda 6 / MX-5
