The 5% nickel content provides superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity. KPMI® guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, which promotes high performance and endurance.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTensilite® Titanium valves feature one-piece U.S.-milled titanium alloy construction with a hard chromium nitride (CRN) shell; CRN offers excellent resistance to impact, abrasion and corrosion\u003c\/li\u003e\n\u003cli\u003eBlack Diamond™ valves feature one-piece stainless steel construction with stellite tips and special impregnation to improve wear properties and reduce friction\u003c\/li\u003e\n\u003cli\u003eWhite Diamond® valves feature one-piece construction and hard chrome stems\u003c\/li\u003e\n\u003cli\u003eAll valves are compatible with OEM and KPMI® valve guides and spring kits\u003c\/li\u003e\n\u003cli\u003eAll valve guides are made of Ampco-45, a high-performance compound with 80% copper content to provide great heat conductivity and 5% nickel content for wear resistance\u003c\/li\u003e\n\u003cli\u003eSpring sets contain springs and titanium upper collars; lower collars included as required; spring kits are engineered for use with standard and oversized valves\u003c\/li\u003e\n\u003cli\u003eKeepers are not included\u003c\/li\u003e\n\u003cli\u003eValves and guides are sold each; spring kits come complete for one motor\u003c\/li\u003e\n\u003cli\u003eMade in the U.S.A.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KPMI","offers":[{"title":"Default Title","offer_id":47232344096955,"sku":"CCP-191-51004","price":18.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/5230\/6875\/files\/82902_0_1.jpg?v=1764609413","url":"https:\/\/motomentum.com\/products\/kpmi-exhaust-valve-guide-bronze-mpn-30-30620","provider":"Motomentum","version":"1.0","type":"link"}
