Radium Engineering Fuel Rail - Mazda 3 MPS (BK / BL) / 6 MPS (GG)
This Radium Engineering fuel rail is a direct-fit upgrade for the Mazda 3 MPS (BK/BL) and Mazda 6 MPS (GG) with the turbocharged DISI engine. It is CNC machined from extruded 6063 aluminium, black anodised and laser etched, with a large bore to support higher fuel demand (SKU 20-0503-02).
The 14mm injector bores match the factory rail so OEM or OEM-equivalent injectors fit, and provisions for the factory retaining clips are retained. Phenolic spacers and washers insulate the rail from cylinder head heat, and the ports are tapped 8AN ORB.
Note: Pair with the Radium plumbing kit 20-0503-PK (sold separately) for a simple connection to the factory fuel lines. For upgraded injectors, confirm 14mm O-ring fitment with your injector supplier. Installation by a professional is recommended.
