Bosch Gasoline Injector 62399 — OE-style fuel injector, ethanol-compatible with seals for Ford/Lincoln/Mazda/Mercury fit

Bosch Gasoline Injector 62399 is a ready-to-install original-equipment style fuel injector engineered to restore precise spray pattern, reliable warm-start behavior, and reduced emissions.

Backed by Bosch’s decades of fuel-system development and over a billion injectors produced, this injector is built to match OE flow rates and spray characteristics for compatible Ford, Lincoln, Mazda and Mercury applications. Constructed from high-alloy steels with protective plastic coverings and supplied with installation seals and O-rings, it’s designed for corrosion resistance, ethanol compatibility and long service life. Use the vehicle fitment checker to confirm compatibility—engine variations affect fit.

How does this injector improve engine performance?

Replacing a worn or leaking injector with the Bosch 62399 brings fuel delivery back to factory specifications so the engine receives the correct fuel/air mixture. That helps combustion efficiency, smoother throttle response, and more consistent starting behavior when the engine is warm.

• Precision-machined nozzle delivers the original spray pattern for complete atomization.
• Calibrated flow rates match OE specifications to prevent run-rich or run-lean conditions.
• Improved warm-start response compared with degraded injectors.

Will this injector resist corrosion and ethanol damage?

Yes—Bosch designs these injectors using premium high-alloy steels and protective plastic coverings that resist corrosion in modern fuels, including ethanol blends. The materials and coatings extend service life and reduce the risk of internal corrosion that can alter spray patterns.

• High-alloy steel body for chemical and mechanical durability.
• Protective plastic coverings to shield electrical and exterior surfaces.
• Engineered for compatibility with ethanol fuels (E100-capable in design).

Are seals and hardware included, and is installation straightforward?

Yes — the injector ships with the necessary seals and O-rings so it’s ready for direct installation upon arrival. Because Bosch ensures OE fit, form and function, installation is typically plug-and-play when matched to the correct vehicle and engine specification.

• Includes new seals and O-rings to prevent vacuum or vapor leaks.
• OE-style electrical connector and mounting dimensions for direct replacement.
• Verify vehicle-year and engine fitment before installation to ensure compatibility.

Which vehicles and part numbers does this replace?

The Bosch 62399 is designed to replace several OE part numbers and fits multiple Ford, Lincoln, Mazda and Mercury models—fitment depends on engine variant. Always confirm the injector matches the vehicle’s engine code using the fit checker or VIN to avoid mismatches.

• Replaces OE numbers such as 7T4Z9F593B, CY0113250, ZZJ113250A.
• Commonly compatible with Ford Edge, Flex, Fusion, Taurus and Taurus X (select years).
• Also fits Lincoln MKS, MKT, MKX, MKZ plus Mazda CX-9 and 6, and Mercury Sable (select years).

Who is this for: The Bosch Gasoline Injector 62399 is intended for DIY mechanics and professional technicians who need an OE-quality replacement injector that restores factory fuel delivery. It’s ideal if you’re addressing poor warm-starting, uneven idle, fuel smell or suspected injector leakage on the compatible Ford, Lincoln, Mazda or Mercury models. Make sure to verify engine-specific fitment before purchasing to ensure a correct, plug-and-play replacement.
