Frequently Asked Questions
Do I need tuning with an R4 injector?Yes—R4 (~115% over) requires custom calibration to control idle quality, balance rates, smoke, and EGT. We also recommend a supporting turbo and fuel system.
Will aftermarket connector tubes void my warranty?Yes. Use only OEM Bosch or Cummins connector tubes to prevent sealing issues and to keep your injector warranty valid.
Is this sold individually or as a set?Individually (qty 1). Order six for a complete set.
What else should I replace during install?Fresh connector tubes, injector seals, and verify your lift pump/filtration. See Recommended Parts above.
