DENSO has started to sell IRIDIUM TT spark plugs having a φ0.4 mm iridium alloy center electrode and a 0.7 mm needle-type platinum alloy ground electrode.

– The quenching effect has been decreased by forming the electrode into a double needle shape. As a result, the flame kernel rapidly develops and the engine’s power is drawn out to its maximum potential.
