DDP N305-350 New 150% Over Injector Set for 5.9 Cummins (2003–2004)

Unlock serious fuel delivery for your early 5.9L Cummins with the Dynomite Diesel Performance (DDP) N305-350 brand-new injector set. These injectors flow 150% over stock and feature body modifications designed for high-output builds, supporting up to approximately 1,200–1,275 RWHP when paired with dual CP3s (or equivalent high-flow supply), large turbos, and proper tuning.

Each set is precision flow-matched and balanced for consistent performance across all cylinders. Brand-new construction means no core charge and no used components.
