Denso Iridium Power Spark Plug

The Denso ITV20 Iridium Power spark plug is engineered for enhanced ignition performance. It utilizes a 0.4mm iridium-tipped, laser-welded fine wire center electrode, which significantly reduces the voltage needed from the ignition system, leading to improved firing. This design contributes to a more powerful and efficient spark. Complementing these features are machine-rolled threads that ensure reliable installation and removal without seizing or cross-threading. Each plug is 100% pre-fired to guarantee the highest quality and performance right out of the box. The insulator is constructed from purified alumina powder for exceptional strength and thermal conductivity, with five ribs to prevent flashover. A copper-glass seal ensures a gas-tight connection between the center electrode and the insulator.
