Product Details

Standard Ignition FJ28 is engineered as a fuel injector replacement for vehicles that need balanced fuel delivery and consistent atomization. The remanufactured design restores injector function for drivability concerns tied to uneven fueling, while the top-feed MFI layout and 2-terminal blade connection support straightforward electrical integration. This part cross-references Bosch 15521 for the same application.

Installation Notes and Tips

Verify connector style, fuel system type, and engine application before installation. Inspect the fuel rail, electrical connector, and sealing surfaces for wear or contamination, and replace damaged seals as needed. Confirm the vehicle’s original injector specification matches the FJ28 design before service.
