EGR Delete Kits

Quick Answers: EGR Delete Kits

• What does an EGR delete kit do?

  An EGR delete kit removes the Exhaust Gas Recirculation system from your diesel engine's intake loop. The OEM EGR pulls hot, soot-laden exhaust back into the intake manifold to reduce NOx emissions — but it also raises intake charge temperatures and deposits carbon through the intake and on intake valves over time. Deleting it keeps the intake clean and charge temps lower.

• Does an EGR delete require a tune?

  Yes, always. The ECM monitors EGR flow via differential pressure and temperature sensors in a closed-loop strategy. Without a tune, the truck will set fault codes immediately when EGR flow drops to zero and may derate or enter limp mode. A proper tune disables the EGR diagnostic monitors and recalibrates fueling and boost targets to account for the change in intake air mass.

• What is a 6.7 Cummins EGR delete kit?

  A 6.7 Cummins EGR delete kit blocks off the EGR cooler inlet and outlet and removes the EGR valve from the intake horn. Kits include billet aluminum or steel block-off plates machined to the OEM flange spec, along with coolant bypass fittings to keep the cooling circuit intact. Paired with a tune, it eliminates one of the primary sources of carbon buildup on the 6.7 platform.

• What is a 6.7 Powerstroke EGR delete kit?

  The 6.7 Powerstroke EGR system routes exhaust through a high-pressure and low-pressure EGR circuit — both must be addressed for a complete delete. A full EGR delete kit for the 6.7 Power Stroke includes block-off plates for both circuits, coolant re-route fittings, and a tune that disables both HP and LP EGR control strategies in the PCM.

• Can I do an EGR delete without a full DPF delete?

  Yes — EGR and DPF are independent systems and can be deleted separately. Many owners start with the EGR delete to solve intake carbon buildup and overheating EGR cooler issues, then address the DPF separately. The tune must be updated to reflect each change. Running an EGR delete tune without the DPF removed will still function, but a combined tune is more efficient.

• Will an EGR delete fix overheating on my diesel?

  It depends on the root cause. If overheating is driven by a failed EGR cooler dumping coolant into the intake — a known failure mode on several platforms including the 6.7 Powerstroke and 6.7 Cummins — then yes, removing the EGR cooler from the circuit eliminates that failure point entirely. If overheating stems from a different source, the EGR delete alone won't resolve it.
