Take your 2003–2007 Ford 6.0L Powerstroke to the next level with our Premium Swag Performance Injector Set, engineered for drivers who want enhanced fuel delivery and stronger performance without stepping into extreme aftermarket territory. These injectors combine reman-built stock-style bodies with 30% over-sized nozzles to improve fuel atomization and flow — giving you smoother power delivery, better throttle response, and expect +40HP performance gains.
Why This Injector Set Stands Out
-
Stock Body Fitment – Maintains OEM dimensions for easy installation and fitment compatibility with original fuel system hardware.
-
30% Over Nozzles – Larger nozzle orifices increase fuel flow up to 30%, improving combustion efficiency and supporting power upgrades with stock-to-mild-mod builds.
-
Premium Remanufacturing – Injectors are fully rebuilt with new internals, including new & improved spool valves and precision-matched flow rates to ensure balanced performance across all cylinders.
-
Balanced Performance & Durability – Designed for both daily drivers and performance-oriented builds that want extra fueling without extreme tuning.
-
Improved Fuel Atomization – Larger nozzles help optimize spray patterns for more complete combustion, which can lead to better throttle response and potential gains in mid-range power.
Fitment & Compatibility
✔ Fits 2003–2007 Ford 6.0L Powerstroke diesel engines (Super Duty trucks, Excursion, vans, etc.).
Performance Enhancements
These injectors are an ideal choice for truck owners running:
-
Stock to mild performance upgrades
-
Tow rigs needing improved throttle response
Injector Installation, Torque Requirements & Warranty Notice
Proper Injector Torquing Is Critical
Correct injector installation and proper torque procedures are essential for 6.0L Powerstroke injectors to operate correctly. Under-torqued or over-torqued injectors can lead to fuel leaks, compression loss, combustion gas blow-by, injector damage, or hard-start conditions. Improper torque can also cause injector movement within the bore, leading to premature failure of internal components.
Injector Stiction & Swag Performance Advantage
Like all 6.0L Powerstroke injectors, stock injectors can suffer from stiction issues over time due to worn spool valves and internal friction. Swag Performance premium injectors are remanufactured with revised internal parts and improved spool valves, reducing stiction and enabling quicker, more reliable injector response. This upgrade helps deliver smoother cold starts, steadier idle, and improved drivability — making them a strong choice for both performance enthusiasts and everyday drivers alike.
For best results, always:
-
Follow Ford-specified torque values and sequences
-
Use new O-rings and seals
-
Ensure injector bores are clean and free of debris
-
Verify hold-down bolts are properly seated and torqued evenly
Failure to follow proper installation procedures can result in injector damage that is not related to manufacturing defects.
