{"product_id":"ik22-iridium-spark-plug","title":"IK22 Iridium Spark Plug","description":"The Denso IK22 High Performance Iridium Plug represents the pinnacle of spark plug technology, offering superior longevity and enhanced combustion. Engineered through continuous research and development, these Iridium plugs boast an impressive lifespan of up to 60,000 miles.\n\nThe IK22's design capitalizes on the properties of iridium to deliver a more potent spark at a reduced voltage. This efficiency allows for wider spark plug gaps, which typically translate into marginal yet valuable increases in engine power. For enthusiasts where every horsepower counts, these plugs are a recommended choice, even utilized in competitive racing environments like the SCCA Spec Miatas.\n\nKey technological advancements include the U-Groove ground electrode, patented in 1972, which promotes better ignitability and a larger flame front for more complete combustion, even with lean air-fuel mixtures. Furthermore, the ultra-fine 0.4mm center electrode, the world's smallest, significantly reduces voltage requirements while dramatically improving firing performance. The tapered cut on the ground electrode also minimizes heat loss and vibration load, allowing the spark plug to withstand demanding driving conditions.\n\nSpecific heat range recommendations are provided: the IK22 is ideal for chipped 1.8t engines and for VR6 engines equipped with turbochargers or superchargers. It is important to note that these are UNGAPPED plugs and are susceptible to damage if gapped improperly; purchasers are advised to consider the pre-gapped versions if unsure.","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":52867537830200,"sku":"HW-PLUGS-IK22","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687954217.webp?v=1787911783","url":"https:\/\/store.motormia.co\/products\/ik22-iridium-spark-plug","provider":"MOTORMIA","version":"1.0","type":"link"}
