These rails are designed to replace the stock fuel rails on a 1993-2001 Mazda RX-7 when upgrading the fuel system*. They are made of machined aluminum and come only with the hardware to assemble them, the bolts to mount the secondary rail to the lower intake, and 1 replacement bolt to help with clearance for the block off plate on the inside of the lower intake manifold. The rails are tapped and threaded 3/8" NPT for fittings to the fuel lines and are designed for 720cc top feed primary injectors and 1600cc top feed secondary injectors*. The increased inside diameter of the fuel pathway through these rails allows increased fuel flow translating to your horsepower needs.

The rails are sold as a set, primary and secondary, for $215 shipped*. Individual rails are available for the cost including shipping of $80 for the primary only and $150 for the secondary only. Also available in anodized blue, red, or black in group buy situations for additional cost of $15 per rail*. Payment by paypal (use Paypal button to left), or money order*. Kits including injectors are also available - email for pricing and availability.
