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\u003eGuide profiles are designed to be as clean and unobstructive to the airstream as possible, while maintaining critical cross sectional thickness in high-temperature areas, promoting both high performance and endurance\u003c\/li\u003e\n\u003cli\u003eIn many instances, because of the nose shape, just the installation of Kibblewhite guides with no other modifications will enhance airflow\u003c\/li\u003e\n\u003cli\u003eWhere the factory base washer allows for it, guides have a flange that sets the protrusion at a height that allows for correct seal to retainer clearance for the most aggressive cam available at the time the guides are designed\u003c\/li\u003e\n\u003cli\u003eOnce the flange touches the head you're home\u003c\/li\u003e\n\u003cli\u003eNo time lost stopping to measure guide protrusion several times during installation\u003c\/li\u003e\n\u003cli\u003eIn cases where a flange would interfere with the factory base washer fitment, a small decrease in diameter above the purchase area marks the correct guide protrusion\u003c\/li\u003e\n\u003cli\u003eVery tight concentricity tolerances are held to ensure the best possible geometry between the seat and guide is maintained when the guides are replaced\u003c\/li\u003e\n\u003cli\u003eThis means minimal material removal from the seat, time savings, and consistent chamber volumes, when valve jobs are performed with KPMI guides installed\u003c\/li\u003e\n\u003cli\u003eA radius at the transition from the nose profile to the main body of the guide prevents galling on installation\u003c\/li\u003e\n\u003cli\u003eC630 Racing Bronze material contains 80% copper alloyed with 5% nickel, and 10% aluminum\u003c\/li\u003e\n\u003cli\u003eHigh-copper content (20% greater than traditional manganese bronze materials) gives excellent thermal qualities\u003c\/li\u003e\n\u003cli\u003eHigh-nickel content makes the guide harder and more wear and corrosion resistant than other bronze materials\u003c\/li\u003e\n\u003cli\u003eAluminum content brings characteristics that make the guides especially compatible with aluminum cylinder heads\u003c\/li\u003e\n\u003cli\u003eMaterial is mill certified, guaranteeing a consistent premium grade of material in every production run; this unique blend of materials create a guide that is extremely resistant to galling, which allows for tighter clearances than other materials\u003c\/li\u003e\n\u003cli\u003eThis reduction in clearance creates a better valve-to-seat seal, and superior oil control\u003c\/li\u003e\n\u003cli\u003eSold in sets of two, unless noted otherwise\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":47232423264443,"sku":"CCP-191-54005","price":23.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/5230\/6875\/files\/82926_0_1.jpg?v=1764610052","url":"https:\/\/motomentum.com\/products\/kpmi-intake-valve-guide-bronze-mpn-80-80770","provider":"Motomentum","version":"1.0","type":"link"}
