Product Details and Specifications

This Standard Ignition fuel injector (part number FJ315RP8) is built to meet OEM standards, making it a direct replacement for original equipment on compatible vehicles. The injector features a plug-in attachment method, simplifying the installation process without the need for additional hardware. Its black finish helps protect against environmental wear, while the included o-rings and seals ensure a tight, leak-free connection within the fuel injection system.

Designed specifically for multi-port fuel injection (MFI) systems, this injector supports gas fuel delivery and is equipped with male blade terminals (two terminals) for secure electrical connections. The absence of retainer clips means installation requires attention to proper seating and securing of the injector in the fuel rail.
