The 'S' in BP5S often denotes a short 9.5 mm (3\/8-inch) reach meant for older, shallow-reach iron heads, which will leave exposed threads in a long-reach hole and cause carbon fouling or misfires.\u003c\/span\u003e\u003c\/h4\u003e","brand":"Corvette Australia Express Parts","offers":[{"title":"Default Title","offer_id":54397720887662,"sku":"106429","price":7.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5744\/8814\/files\/106429.jpg?v=1785193031","url":"https:\/\/corvetteaustraliaexpressparts.com\/products\/ngk-bp5s-spark-plug-cast-iron-heads-small-block-each","provider":"Corvette Australia Express Parts","version":"1.0","type":"link"}
