{"product_id":"ruthenium-hx-single-spark-plug","title":"Ruthenium HX Single Spark Plug","description":"The NGK 95605 Ruthenium HX spark plug is engineered for today's efficient engines that demand high ignitability and durability. Its advanced technology addresses the shorter lifespan of traditional spark plugs in modern, high-performance, and fuel-efficient designs.\n\nKey features include a 0.4mm Ruthenium alloy fine wire center electrode and a 0.8mm platinum fine wire ground electrode, contributing to superior oxidation resistance and anti-seizing properties. The Projected Square Platinum Electrode (PSPE) design enhances spark energy concentration, igniting a wider range of air-fuel ratios for improved performance in both rich and lean engine conditions. Corrugated ribs on the insulator prevent flashover, while the pure alumina silicate ceramic insulator offers superior strength and heat transfer. A copper core further aids in heat removal.\n\nThis spark plug is pre-gapped to 0.032 inches (0.8 mm), but it may require minor adjustments using a spark plug gap tool to match your specific engine's OE-recommended specifications. For optimal engine performance, gaps should be within ±0.004 inches of the recommended value. The longevity of these plugs is estimated between 60,000 to 120,000 miles, with a 60-day warranty provided.","brand":"NGK","offers":[{"title":"Default Title","offer_id":52663099851064,"sku":"NGK-95605","price":9.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687077068.jpg?v=1784323810","url":"https:\/\/store.motormia.co\/products\/ruthenium-hx-single-spark-plug","provider":"MOTORMIA","version":"1.0","type":"link"}
