FAQ
How much power will 80% over injectors support?Power potential depends on turbo, pump, and tuning, but 80% overs are a major step beyond stock and suitable for competition-oriented builds.
Do I need a lift pump with these injectors?Yes, a quality lift pump and proper filtration help maintain rail pressure and protect injectors — see our 03–07 Lift Pumps category.
Will these fit late 2004.5 trucks?These are for early 2003–2004 common-rail 5.9L applications. Verify build date/fitment before ordering.
Are the injectors individually or set-matched?They are matched as a set with tight flow variance and validated across multiple pressure/energizing points.
