Keep clean, precisely metered fuel flowing to every cylinder with the Standard Ignition Fuel Injector FJ953, a 100% new top-feed MFI (multiport fuel injection) injector built with no remanufactured components. It installs as a direct-fit replacement on the 2004 Ford F-150 and 2004 Ford Lobo equipped with the V8-5.4L engine, and is specifically designed for Ford engines.
A fuel injector sprays atomized fuel into the intake on command from the engine control system; worn or clogged injectors can show up as rough idle, hesitation, hard starting, or reduced fuel economy. If a failed injector is the cause, this replaces it.
- Engine-specific calibration: laser-drilled metering discs and a high-precision nozzle are designed to control fuel flow rate and spray pattern to help restore proper atomization and support normal fuel economy.
- Corrosion resistance: brass terminals plus a stainless steel calibration slide and spring are designed for consistent, long-term performance.
- Optimized sealing: high-temperature Viton O-rings (included) help maintain proper sealing and guard against fuel leaks. Mounting hardware is not included.
- Tested & made in the USA: end-of-line tested and calibrated, designed and manufactured in Greenville, SC.
