{"product_id":"fr6ahx-s-double-fine-electrode-spark-plug","title":"FR6AHX-S Double Fine Electrode Spark Plug","description":"The NGK FR6AHX-S Ruthenium HX spark plug is engineered to meet the demands of modern engines, prioritizing high ignitability for optimal combustion. Its Double Fine Electrode (DFE) design is specifically crafted to enhance spark energy concentration, allowing for ignition across a broader spectrum of air-fuel ratios. This advanced design leads to improved performance, particularly in engines operating under rich or lean conditions.\n\nKey construction elements include a 0.4mm Ruthenium alloy fine wire center electrode, known for its exceptional durability and high melting point, paired with a 0.8mm platinum fine wire ground electrode. This combination ensures a strong, consistent spark. The spark plug also benefits from trivalent metal platinum plating on its components, offering superior resistance to corrosion and seizing, which contributes to a longer service life.\n\nThe pure alumina silicate ceramic insulator provides exceptional mechanical strength and efficient heat transfer, crucial for maintaining stable operating temperatures within the combustion chamber. Complementing this is a copper core that effectively dissipates heat away from the electrode tip, further enhancing thermal management and plug longevity. The NGK FR6AHX-S has a heat range of 6, a 14mm thread diameter with a 1.25mm pitch, and a 19mm reach, with a 5\/8\" (16mm) hex size for installation. It features a gasket seal type and a solid terminal type, with a pre-set gap of .043\" (1.1mm). The unit also includes a resistor with a value of 5k Ohm.","brand":"NGK","offers":[{"title":"Default Title","offer_id":52663098442040,"sku":"FR6AHXS","price":8.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687072980.jpg?v=1784323797","url":"https:\/\/store.motormia.co\/products\/fr6ahx-s-double-fine-electrode-spark-plug","provider":"MOTORMIA","version":"1.0","type":"link"}
