| Legal Use |
Emissions-compliant for road use |
For off-road/race use only—users are responsible for local compliance |
Community Insights & Owner Feedback
-
Some owners prefer to block off EGR flow while leaving the cooler in place—ideal for stealth deletes in emission-inspection states.
-
Complete removal of the EGR system opens up space in the engine bay for better access and future performance mods.
-
When paired with an EZ Lynk tuner and GDP tunes, many users report zero error codes, cooler temps, and noticeably smoother driving.

Benefits & Function
For the 2011–2025 6.7L Powerstroke, the selected EGR hardware blocks the exhaust-recirculation path and provides the matching coolant connections after the specified work. Flow-through hardware includes a coolant passage; Single Board is a different layout that must follow its own instructions. Removing the specified cooler components can improve service access around the engine bay and address recurring EGR-related maintenance.
The existing product information describes cleaner intake airflow, improved response and fuel economy, lower coolant temperatures and reduced EGR repair costs. Up to 20% is a maximum fuel-economy claim, not a guaranteed result. Blocking EGR removes one soot source; it does not make intake air free of every contaminant, clean existing deposits, repair the turbo or fuel pump, or replace the DPF. Regeneration and other aftertreatment functions depend on the complete vehicle configuration.
FAQ
What horsepower and torque does the 6.7L Powerstroke produce?
Output depends on model year and engine version. The earlier FAQ's 475 hp and 1,050 lb-ft figures describe certain versions; later High Output versions can differ. Use Ford's specifications for your truck rather than treating one figure as the rating for all 2011–2025 models.
How often should I change the engine oil?
Follow the truck's oil-life monitor and model-year maintenance schedule. The previous 7,500-mile normal/5,000-mile severe-use guidance should not be applied universally; towing, idling, fuel type, time and operating conditions can change the required interval.
Which engine oil should I use?
The earlier guidance lists 10W-30 for normal use and 5W-40 for more demanding conditions. Select the viscosity and Ford oil specification required by your model-year manual, climate and duty cycle; installing EGR hardware does not change those requirements.
How can I improve fuel economy?
Keep up with maintenance, use appropriate fuel and tire pressures, and consider load and driving conditions. The product states fuel-economy improvements of up to 20% with the relevant configuration; that maximum is not a guaranteed gain for every truck.
What common 6.7L issues does this kit address?
The previous FAQ identifies turbocharger, EGR and high-pressure fuel-pump issues. This hardware addresses the listed EGR connections and related maintenance path; it does not repair turbocharger or fuel-pump failures. Diagnose the actual fault before selecting parts.
Can the engine use B20 biodiesel?
The existing FAQ describes compatibility with up to B20, a blend of 20% biodiesel and 80% petroleum diesel. Follow the truck's fuel-quality requirements and any special maintenance schedule for biodiesel use. The EGR kit does not alter fuel compatibility.
How do I reset the oil-change reminder?
Reset it only after the required oil and filter service. Some model years use the ignition-on accelerator-and-brake procedure with confirmation after about 25 seconds; others use the instrument display. Follow the reset procedure in your specific owner's manual.
What is the truck's towing capacity?
Use the VIN-specific configuration, payload label and applicable Ford towing guide. The earlier FAQ's “up to 37,000 lb” figure applies only to suitably equipped configurations, not every model. This EGR kit does not increase the manufacturer's towing or payload ratings.
How does DPF regeneration work after installation?
On an equipped vehicle, regeneration is normally automatic; manual or service regeneration follows the vehicle's instructions and diagnostic requirements. EGR hardware alone is not a DPF delete and does not establish that regeneration has been removed or is unnecessary.
When should the fuel filters be changed?
Follow the model-year schedule, filter monitor where equipped, and special-use requirements. The earlier 15,000-mile/annual guidance is not a universal interval for every 2011–2025 truck or fuel type; time, engine hours and biodiesel use can also matter.
Can I block EGR flow while retaining the cooler?
The existing product information discusses retaining the cooler, which differs from full cooler removal. The required parts, coolant path and remaining cooler maintenance depend on the chosen configuration. Follow the instructions for that layout rather than assuming all plate styles use the same procedure.
What if I omit the coolant bypass or matching plate?
The coolant circuit must be completed and sealed as required by the selected layout. Omitting a required plate, seal or connection can cause coolant circulation or leakage problems. Do not interchange Flow through plate and Single Board procedures.
Will the exhaust brake and manual gear selection still work?
The existing FAQ states these functions can remain available with compatible calibration. Confirm support for your particular truck and calibration. A specific power-level tune, including the previously mentioned 75 hp tow setting, is not a universal compatibility or reliability guarantee.
How do I choose the correct year group?
Select 2011–2014 & 2017–2019, 2015–2016, or 2020+ according to the actual model year. The stated product fitment ends at 2025. The 2015–2016 versions include an additional tube assembly; confirm the correct plate style and packing list as well.
Are Flow through plate and Single Board the same?
No. Their plate construction and coolant hardware differ. Flow-through hardware has a coolant passage, while Single Board is a different listed layout. Use the selected version's complete instructions and verify the matching connections instead of assuming interchangeability.
Does the CCV Reroute option include the EGR kit?
No. “11-25 CCV Reroute,” SKU SPKT26010, is separately listed with its own components. It is not a complete EGR kit, and selecting an EGR option does not automatically include the CCV package.
Can I retain the factory EGT probe?
The product lists a tapped exhaust cover plate for the Ford factory EGT probe. Install the probe or matching adapter according to the instructions for the supplied year-specific hardware; do not assume the port details are identical across versions.
Is a tuner included, and can I expect zero error codes?
No tuner or calibration is listed as included with these EGR hardware options. Use compatible calibration and confirm the requirements for the truck's configuration. Reports involving EZ Lynk or GDP tunes do not guarantee fault-free operation for every setup.
Is this kit legal for public-road use?
It is marketed for off-road/race use and is not for public-road emissions-controlled vehicles. An off-road label or stock-looking engine bay does not itself create an emissions-law exemption. Confirm applicable requirements before purchase or installation.
