Improve Performance and Efficiency

The factory fuel injectors in the 2003-2004 F250 & F350 have done the job admirably, but the 6.0L Powerstroke has quite a few years under its belt.

Sinister Diesel carries these 100% new fuel injectors built from remanufactured body to provide a high-quality OE injector at an approachable price point. Featuring new injector coils and harness assemblies, a new electrical connector, and a new and redesigned spool valve to avoid stiction, this new injector unit by Sinister Diesel will improve injector response as well as performance in cold weather conditions.
