Important Notes

• Highly recommended to install a boost elbow when using the factory turbo with a tuner or boost fooler.
• Early 1998.5 engines (serial number below 56462598) may require new connector tubes for proper sealing.

The DDP ISB-50 Stage 1 injectors give you a noticeable power bump and better drivability without the extra smoke or noise of larger injectors. A proven, reliable upgrade for 2nd-gen 24-valve Cummins owners.
