Description

The rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. Like the OEM fuel rails, the injector bores are 11mm ID so factory injectors are permitted. This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused and phenolic washers are included to thermally insulate the fuel rail from the aluminum intake manifold.
