Install Notes
- Always replace injector connector/supply tubes during install to avoid back-leak and contamination issues.

- Big injectors require adequate turbo airflow (e.g., S400/compounds) and appropriate tuning.
FAQ
How much power will the 0986435503SE-R6 support?Industrial Injection designates this as a Race 6 (~400HP) level injector set with ~70 LPM total flow potential. Actual results depend on turbo(s), CP3 volume/pressure, fuel quality, and tuning.
Do I need to upgrade my CP3 and lift pump? Yes. For 192% over nozzles, a high-flow lift pump and at least a stroked or dual CP3 setup are strongly recommended to maintain rail pressure under load. See our CP3 & Dual Fueler section.
Should I replace the injector supply/connector tubes? Yes. Contamination or sealing issues with old tubes can cause misfire and premature injector wear. See Cummins 4988806 supply tube as an example.
Is this CARB legal for on-road use? No. These Race 6 injectors are intended for competition/off-road use and are not CARB approved.
What's the warranty? Manufacturer policy is 1-year, unlimited mileage against defects. Core return rules apply.
