Oversize – 2017–2025 M8","description":"\u003ch2\u003eKibblewhite KPMI, Inconel White Diamond Valve, Exhaust. Oversize – 2017–2025 M8\u003c\/h2\u003e\n\u003cp\u003eInconel with hard chrome finish. Standard size replacement with oversized head. Dimensions: 1.284\" head dia. x 0.2342\" stem dia. x 4.050\" overall length. KPMI valves are manufactured in the U.S.A. by a dedicated staff and personnel with hands-on experience in stock and high performance. Quality materials and the latest CNC and 3-D computer modelling equipment make sure each and every Kibblewhite Precision Machining valve train component is top of the line. Inconel is a special heat resistant so-called ''Superalloy''. By nature of the material it cannot be black nitrided so it is hard chromed. It has a superior heat resistancy against issues like exhaust valve stem bending; of OEM M8 exhaust valves; without impact. 6mm is thin especially when dealing with extremities as detonation; lean mixtures and poor timing curves. Inconel''s superior heat resistance will maintain its strength longer at higher temperatures; it is therefore used for the thin stems on M8 exhaust valves only.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003e17-25 M8\u003c\/p\u003e\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Kibblewhite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e MOTOR PARTS \u0026gt; VALVES EXHAUST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e 597866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kibblewhite","offers":[{"title":"Default Title","offer_id":57372733735299,"sku":"MCS597866","price":39.09,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1329\/4265\/files\/597866k.jpg?v=1775139423","url":"https:\/\/hogparts.com\/products\/mcs597866","provider":"Hogparts UK Ltd","version":"1.0","type":"link"}
