The 5 percent nickel content provides superior resistance to wear, and the 80 percent copper content delivers outstanding heat conductivity. Guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, promoting 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":47232551289019,"sku":"CCP-532388","price":43.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/5230\/6875\/files\/333682_0_1.jpg?v=1764611128","url":"https:\/\/motomentum.com\/products\/kpmi-intake-valve-guide-bronze-mpn-30-32820","provider":"Motomentum","version":"1.0","type":"link"}
