These plugs come pre-gapped to 0.028\" from HKS which is suitable for use but we suggest closing the gap down to 0.022\" for maximum performance applications.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/span\u003eWe are frequently asked which plugs are better for the Kia\/Hyandai platform, HKS, or Denso. We've used both brands on our development cars and have found both to be good quality. Generally speaking HKS plugs tend to offer a longer life of 20-35k miles before they need to be replaced, while Denso plugs tend to only last 15-25k miles before needing replacement. For that longer life you do pay a price premium. We've found timing corrections and overall engine performance between them to be otherwise equivalent. \u003c\/p\u003e\n\u003c\/div\u003e","brand":"JDM Purist","offers":[{"title":"4 PACK","offer_id":45621628960931,"sku":"50003-M45IL-1","price":135.0,"currency_code":"USD","in_stock":true},{"title":"6 PACK","offer_id":45621628993699,"sku":"50003-M45IL-2","price":165.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/9336\/9763\/files\/HKS_High_Performance_Spark_Plugs.webp?v=1739898044","url":"https:\/\/www.jdmpurist.com\/products\/hks-high-performance-spark-plugs","provider":"JDM Purist","version":"1.0","type":"link"}
