{"product_id":"iridium-spark-plug-85","title":"Iridium Spark Plug","description":"The NGK IX Iridium Spark Plug 6510 is engineered to deliver superior performance through its advanced design and materials. The core of this spark plug is its iridium center electrode, which is noted to be six times harder than platinum, contributing to exceptional acceleration and improved fuel efficiency.\n\nThese spark plugs are designed with a 14mm thread size and a 1.25mm thread pitch, a 25mm reach, and a 5\/8\" hex size. The pre-gap size is 1.1mm, though some users note they can be adjusted for specific tuning needs, with recommendations to gap them as low as .026” or .040-.044” out of the box. The heat range is 7, and it is considered one step colder for certain applications, making it suitable for modified and tuned engines, particularly those with power adders or running higher boost levels.\n\nCustomer reviews indicate that these plugs are a popular choice for performance-oriented vehicles, including those with Ecoboost engines, Coyote engines, Gen 3 Hemis, and Mazdaspeed applications. Some users have reported success using them on heavily cammed Vipers and boosted Mustangs. However, there have been isolated reports of receiving faulty or used plugs, and one user noted they can foul quickly. It is recommended to replace these plugs every 12,000-15,000 miles for optimal performance.","brand":"NGK 6510","offers":[{"title":"Default Title","offer_id":52663101456696,"sku":"NGK-6510","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687077224.jpg?v=1784323823","url":"https:\/\/store.motormia.co\/products\/iridium-spark-plug-85","provider":"MOTORMIA","version":"1.0","type":"link"}
