The AFI fuel rail kit is designed to replace the restrictive factory fuel rail while increasing performance and adding style. The rail is machined from 6061 Aluminum, and then anodized per Mil-spec-A-8625. With the largest bore on the market, this rail will outflow the competition. Our modular design makes upgrading simple. The rail is compatible with all factory lines, yet is easily adaptable to AN lines once more power is desired. Available in Black and Red
