{"product_id":"pro-series-cylinder-head-stud-kit-4","title":"Pro Series Cylinder Head Stud Kit","description":"The ARP 201-4304 Pro Series cylinder head stud kit is engineered to replace stock head bolts in MINI 1.6L N12, N14, N16, and N18 engines, particularly for applications involving significant boost or racing. These studs are constructed from a premium grade 8740 alloy, exceeding \"aircraft\" quality standards, and are heat-treated to 200,000 psi. The cold-forging process and post-heat-treat threading significantly enhance their fatigue strength, offering superior durability compared to standard bolts.\n\nThe use of studs simplifies engine assembly and allows for more accurate and consistent torque loading, as they stretch only on the vertical axis when torqued, unlike bolts which can be twisted.\n\nEach kit includes hardened parallel washers for even load distribution and precise torque readings, along with lubricant. ARP emphasizes the quality and performance of their fasteners, manufactured in the USA to exacting aerospace standards. This kit is specifically designed to fit all Gen 2 MINI N12, N14, N16, and N18 engines.","brand":"ARP Head","offers":[{"title":"Default Title","offer_id":52686992703800,"sku":"201-4304","price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687888438.webp?v=1784879244","url":"https:\/\/store.motormia.co\/products\/pro-series-cylinder-head-stud-kit-4","provider":"MOTORMIA","version":"1.0","type":"link"}
