A-Premium Fuel Injectors Set of 8 for Ford 4.6L V8 — Direct-Fit, OE-Style Spray Atomization

A-Premium Set of 8 Fuel Injectors is a direct-fit replacement for 4.6L V8 Ford and Mercury engines, engineered to restore precise fuel delivery and consistent spray atomization.

These eight fuel injectors are designed to match OE fitment and electrical connections for selected Ford F-150, E-150, E-250, Explorer, and Mercury Mountaineer models from 2004–2008 with the naturally aspirated 4.6L V8. Each injector uses a two-terminal blade connector and is built to deliver a fine mist for improved combustion consistency. The set ships with a one-year unlimited-mileage guarantee from A-Premium and several manufacturer reference numbers for easy cross-referencing at purchase time.

Which vehicles will these injectors fit?

These injectors are intended for specific Ford and Mercury applications with the 4.6L V8 engine. Confirm fitment by matching year, model, engine size, and reference numbers before installation.

• Ford F-150 and E-150 models: 2004–2008
• E-150 Club Wagon and Explorer: 2004–2005
• Ford E-250: 2005–2008

How do these injectors affect engine performance and efficiency?

Well-atomized fuel spray helps promote more uniform combustion across cylinders, supporting smoother idle, steadier throttle response, and potentially more consistent fuel economy. These units are designed to restore the injector nozzle pattern and flow characteristics expected for the factory system.

• Precision nozzle design for improved fuel atomization
• Balanced flow across all eight injectors to reduce cylinder-to-cylinder variation
• Direct electrical and mechanical compatibility to maintain system timing

What electrical and physical specifications should I check?

These injectors use a two-terminal, male blade-style electrical connector — verify connector type and orientation before purchase. They are built for gasoline fuel systems and match OE-style mounting and sealing dimensions for a straightforward swap.

• Fuel type: Gasoline
• Terminal gender: Male; terminal count: 2; terminal type: Blade
• OE reference numbers included for cross-checking: FJ867, 800-1903N, CM-5171, and others

Who is this for: This A-Premium set is meant for vehicle owners, mechanics, and fleet managers who need a full-bank replacement for 4.6L V8 Ford and Mercury engines.
