Introduction
Thank you for choosing the SPETUNER 6.7 powerstroke egr delete kit. Designed to maximize your engine’s potential, this kit eliminates the restrictions caused by the stock Exhaust Gas Recirculation (EGR) system. By improving airflow, reducing soot buildup, and minimizing long-term maintenance, the EGR delete is a powerful upgrade for off-road and race enthusiasts.
Important Note: This modification is for off-road and race use only and may not comply with emissions regulations for on-road vehicles. Before installing, familiarize yourself with local laws to ensure compliance.
Let’s dive into the step-by-step process to transform your 6.7L Powerstroke into a performance powerhouse!

- Socket Wrenches: Sizes 7mm, 8mm, and others.
- Pliers: For clamps and small parts.
- Sawzall: Optional, for cutting stubborn components.
- Screwdrivers: Both flathead and Phillips.
- Penetrating Fluid: To loosen seized bolts.
- Drain Pails: To catch coolant.
- Safety Gear: Gloves and safety glasses.
SPETUNER EGR Delete Kit Components
- Blocker Plates: Seal off the EGR system ports.
- Gaskets: Ensure airtight connections to prevent leaks.
- Bolts and Washers: Secure the plates and components.
- Hoses and Clamps: Replace stock hoses where necessary.
Before beginning, inspect your kit and tools to ensure everything is ready.
Preparation
Safety First
- Park your vehicle on a flat surface and engage the parking brake.
- Wear safety gloves and goggles to protect yourself during the process.
Disconnect the Batteries
- Use a wrench to disconnect the negative terminals on both batteries. This prevents electrical shorts or accidental startups.
Lift the Vehicle
- Use a hydraulic jack or ramps to raise the front of your truck.
- Place drain pails beneath the radiators to catch the coolant you’ll drain shortly.
Once the truck is secured and prepped, you’re ready to tackle the EGR system.
Step 1: Drain the Coolant
Draining the coolant is crucial to avoid spillage when removing the EGR components.
Locate the Radiator Drain Plugs:
Position drain pails underneath the plugs.
Open the Plugs:
Use pliers to gently turn and pull out the drain plugs (usually plastic). Take care not to damage them.
Remove Coolant Caps:
Open the radiator and coolant reservoir caps to allow air to flow and speed up drainage.
Ensure the coolant is fully drained before moving to the next step.
Step 2: Remove the Air Intake System
Removing the air intake creates the space you need to access the EGR system.
Unbolt the Air Intake Box:
Use an 8mm socket to remove the bolts securing the intake box.
Disconnect the mass airflow (MAF) sensor carefully.
Remove the Intake Pipe:
Loosen the clamp with a 7mm or 8mm socket and gently pull the pipe off the throttle body.
Clear the Workspace:
Remove any additional hoses or brackets attached to the intake system.
With the intake system out of the way, you can now focus on the EGR components.
Step 3: Remove the EGR System
Access the EGR System
Disconnect Coolant Lines:
Identify the hoses connected to the EGR cooler and remove the clamps using pliers.
Unplug Wiring and Sensors:
Carefully disconnect all sensors and wiring harnesses. If access is tight, remove any obstructing brackets.
Remove the EGR Cooler
Unbolt the Cooler:
Remove the six bolts (three on each side) securing the cooler. Use penetrating fluid if the bolts are stuck.
Handle Stubborn Components:
If necessary, use a Sawzall to cut obstructing brackets, ensuring you don’t damage surrounding parts.
Extract the Cooler:
Wiggle the cooler loose and carefully pull it out. Avoid tangling with the injector wiring harness or other sensitive components.
Step 4: Install the SPETUNER EGR Delete Kit
Install the Blocker Plates
Position the Plates:
Place the first blocker plate where the EGR cooler was removed. Use the factory gaskets to ensure a proper seal.
Secure with Bolts:
Fasten the plates with the provided bolts and washers. Ensure they’re tightened to the recommended torque.
Repeat for the Exhaust Port:
Install the second blocker plate on the exhaust side, following the same steps.
Reassemble Components
Reinstall the Intake System:
Reattach the intake pipe and box, securing all clamps and reconnecting the MAF sensor.
Reconnect Coolant Lines:
Reattach all hoses and clamps, ensuring they’re properly seated.
Refill Coolant:
Add the appropriate coolant to the radiator and reservoir. Replace the caps securely.
Reconnect Batteries:
Reconnect the negative terminals to restore power.
Step 5: Testing and Troubleshooting
Initial Checks
- Turn the ignition to the "on" position without starting the engine. Check for warning lights.
- Start the engine and let it idle. Listen for unusual noises and inspect for leaks around the blocker plates and coolant lines.
Road Test
- Take the truck for a short drive. Monitor performance, turbo boost, and any engine codes.
If issues arise, revisit the installation to ensure all components are properly secured.
Step 6: Tune Your Engine
After installing the EGR delete kit, proper tuning is essential for optimal performance.
Choose a Tuning Solution
Use a SPETUNER-compatible tuner designed for 6.7L Powerstroke engines.
Install the Tuner
Follow the manufacturer’s instructions to adjust the engine’s ECU settings.
Test the Results
Conduct another road test, monitoring fuel efficiency, power output, and boost pressure.
Legal Considerations
Installing an EGR delete kit may not be legal for on-road use due to emissions regulations. Always ensure that this modification complies with local laws and is used exclusively for off-road or racing purposes.
