The NGK Ruthenium HX spark plug is a high-ignitability replacement built for modern engines using patented ruthenium tip technology and specialized DFE and PSPE designs to concentrate spark energy. It promotes more complete fuel burn for quicker throttle response, smoother idle and improved cold starts while the ruthenium center electrode enhances durability. Fine-wire electrodes (0.4mm ruthenium center, 0.8mm platinum ground), alumina insulator and trivalent plating aid heat transfer and anti-seize.
