Fuel Rail for NC Mazda MX5 Miata by Radium

Optional 20-0503-PK Information: 
This kit includes all of the necessary adapters making the 20-0503-02 fuel rail a direct OEM fuel rail replacement.

Features:
• Black Anodized Laser Etched Fuel Rail
• Stainless Steel Mounting Hardware
• Thermal Insulating Washers

Overview:
This Radium Engineering fuel rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. Like the original fuel rails, the injector bores are 14mm ID so factory injectors are permitted. Provisions for the OEM injector retaining clips are implemented as well. The rails are compatible with all fuel types including popular alcohol mixtures such as E85. Spacers and washers are included to thermally insulate the fuel rail from the cylinder head.

Appropriate fittings must be selected based on the specific application. Ample space around the fuel rail port(s) is necessary for larger accessories such as fuel pressure regulators, fuel pressure gauges, and fuel pulse dampers. To verify clearance, the dimensional drawings on the product pages can be used as a reference guide.

Fuel Injector Information:
There are two type of fuel rails made by Radium: upgrade rails and top feed conversion rails. Upgrade rails only upgrade the rail and the OEM fuel injectors can be reused. If an upgrade to the injectors is desired, they must be equivalent to the OEM injector, meaning they must be the same height and the upper & lower O-rings must match the OEM diameters and styles. Top feed conversion rails are used to convert a vehicle that has side feed (or sometimes air-assist) injectors over to a top feed injector.

This fuel rail is an upgrade rail. OEM or OEM equivalent injectors must be used.

*Radium does not make fuel injector recommendations*
• Consult your tuner for injector brand or flow rate recommendations.
• Consult the injector manufacturer for a part number that has the correct dimensions.
