{"product_id":"resistorless-spark-plugs","title":"Resistorless Spark Plugs","description":"The Flyin' Miata NGK race spark plugs are an upgrade for high boost vehicles. By eliminating the internal resistor, these plugs ensure that 100% of the spark energy is directed to the arc, which can resolve high-boost misfire problems and allow for a larger spark gap, leading to increased power. This is considered one of the most cost-effective ignition upgrades available.\n\nThese spark plugs are a heat range 7, suitable for high power applications, but may be more prone to fouling if the vehicle experiences starting issues. The manufacturer advises against using anti-seize on these plugs, as they are installed dry from the factory with a trivalent plating that provides corrosion resistance and acts as a release agent.\n\nThese spark plugs are compatible with 1990-05 Miatas and work well with the Flyin' Miata Big Spark kit. However, they are not compatible with the old Link ECU. They are sold in sets of four, which is sufficient for one car.","brand":"Flyin' Miata","offers":[{"title":"Default Title","offer_id":52867545891128,"sku":"04-56205","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687953947.webp?v=1787911852","url":"https:\/\/store.motormia.co\/products\/resistorless-spark-plugs","provider":"MOTORMIA","version":"1.0","type":"link"}
