Denso Iridium spark plug - IK31 - ( for Extreme tuning, heat value 10)

High-quality iridium spark plug with a heat value of 10 for extreme tuning.

Long life compared to traditional copper candles! Reliable operation in both factory and tuned engines!

Its main characteristic is the special iridium electrode. Thanks to the high material density of iridium, it is a good electrical conductor and can withstand very high temperatures (iridium's melting point is 2446 degrees Celsius). Denso uses the properties of iridium to create the extremely thin 0.4 mm electrode tip, for which Denso's patented laser welding is used. This guarantees the creation of a precision end product.
