-Genuine DENSO product -0.4 Millimeter center electrode -Denso iridium series -Price for 1SET (4PCS)
The 0.4-millimeter center electrodehas a low required voltage and high ignitability, that means your vehicle experiences less interference to spark growth (quenching), fewer misfiresand significantly improved combustion, optimizing power outputand fuel economy getting you farther with less gas.
Developed with DENSOs ownoptimized Iridium alloy; this is thesmallest mass-produced center electrode available today.
DENSO selected Iridium and engineered it with Rhodium to build the most durable alloy for spark plugs. The patented formula has the highest concentration of Iridium of any spark plug and outperforms in the most severe engine temperatures resist.
