The DDP ISB-75 Stage 2 75HP High Flow Injectors are the perfect choice for those looking to improve their 5.9 Cummins 1998.5-2002's performance. With a 75 RWHP improvement, these injectors are capable of supplying 420 RWHP with proper supporting modifications. The maximum size injector recommended for stock turbo, the DDP ISB-75 Stage 2 75HP High Flow Injectors offer a mix of excellent fuel economy, added performance, and minimal increase in smoke output.

Note: Highly recommend installation of a boost elbow (when possible) if using a factory turbo and installing a boost fooler or tuner.
