The Ford 6.7L Powerstroke EGR delete is a popular modification to improve engine performance and reduce maintenance. It involves removing the EGR system to enhance power and efficiency while minimizing long-term wear on engine components.
1.1 What is an EGR System?
An Exhaust Gas Recirculation (EGR) system is a component designed to reduce nitrogen oxide emissions by recirculating a portion of exhaust gases back into the engine’s intake system. This process lowers combustion temperatures, reducing harmful emissions. The system includes an EGR valve, cooler, and sensors, working together to regulate gas flow. While it helps meet emissions standards, it can lead to engine wear and decreased performance over time, prompting some owners to consider an EGR delete for improved efficiency and durability.
1.2 Purpose of EGR Delete
The primary purpose of an EGR delete is to eliminate the recirculation of exhaust gases into the engine, which can accumulate soot and cause premature wear on components. By removing the EGR system, drivers aim to improve engine performance, increase fuel efficiency, and reduce maintenance costs associated with clogged coolers and failed sensors. This modification is particularly popular among diesel truck owners seeking enhanced reliability and power output for both on-road and off-road applications.
Benefits of Performing an EGR Delete
Performing an EGR delete on your Ford 6.7L Powerstroke offers improved engine performance, reduced maintenance costs, and increased fuel efficiency. It eliminates EGR-related issues, enhancing overall engine reliability and power output while minimizing long-term wear on components.
2.1 Improved Engine Performance
Deleting the EGR system on your Ford 6.7L Powerstroke eliminates soot buildup and contamination in the engine. This results in a cleaner intake system, allowing for better airflow and enhanced combustion efficiency. With the EGR system removed, your engine can breathe more freely, leading to increased horsepower, torque, and a smoother overall driving experience. This modification is particularly beneficial for drivers seeking optimal performance without the drawbacks of EGR-related issues.
2.2 Reduced Maintenance Costs
Removing the EGR system significantly reduces long-term maintenance costs. The EGR cooler, valve, and associated components are prone to clogging and failure, leading to expensive repairs. By eliminating these parts, you minimize the risk of coolant leaks, sensor failures, and soot buildup in the intake system. This modification also reduces the need for frequent cleaning of EGR-related components, saving time and money over the life of your vehicle.
2.3 Increased Fuel Efficiency
Eliminating the EGR system can lead to increased fuel efficiency by improving engine airflow and combustion efficiency. Without the EGR, intake air is cleaner and cooler, allowing for a more complete burn of fuel. This results in better mileage, especially during highway driving or when towing. While exact savings vary depending on driving conditions, many drivers report noticeable improvements in fuel economy after the EGR delete. This modification is particularly beneficial for those seeking optimal performance and cost savings over time.

Use tools appropriately to avoid damaging components or stripping bolts. If unsure, consult a professional. Follow all safety guidelines to ensure a risk-free installation process for your Ford 6.7 EGR delete.
Step-by-Step Installation Instructions
Begin by removing factory EGR components, then install the delete kit, ensuring all connections are secure. Follow kit instructions for proper fitting and alignment.
4.1 Removing Factory EGR Components
Start by disconnecting the battery to prevent any accidental engine start. Drain the coolant system to avoid leaks when removing the EGR cooler. Carefully disconnect the electrical connectors and vacuum hoses attached to the EGR valve. Use a wrench to remove the EGR cooler from the engine, taking note of the mounting bolts. Gently pull the EGR valve out of its housing, ensuring not to damage surrounding components. Remove all associated piping and set aside any reusable hardware for later installation.
4.2 Installing the EGR Delete Kit
Install the EGR delete block-off plates using the factory gaskets to ensure a proper seal. Tighten the bolts in a star pattern to avoid warping the manifold. Connect the exhaust manifold block-off plate securely, ensuring no leaks. Install the provided up-pipes and Y-bridge, aligning them properly with the exhaust system. Consult the kit’s instructions for specific torque specifications and ensure all connections are tightened evenly. Apply a thin layer of gasket sealant if recommended by the manufacturer. Double-check all connections for tightness before proceeding.
4.3 Connecting and Securing Components
Connect the exhaust manifold to the up-pipes, ensuring proper alignment and gasket sealing. Secure all components using the provided hardware, following the torque specifications. Reattach any sensors or wiring harnesses disconnected during the process. Tighten all connections firmly to prevent leaks; Use thread sealant on threaded fittings if required. Double-check all connections for tightness and inspect for any signs of leaks or misalignment. Ensure the system is properly secured to avoid vibration damage during operation. Follow the kit’s instructions for final tightening sequences.
Post-Installation Considerations
After installation, ensure proper tuning and calibration for optimal performance. Test the system thoroughly to confirm all components function correctly and reliably. Follow the kit’s instructions for final checks.
5.1 Tuning and Calibration
After installing the EGR delete kit, proper tuning and calibration are essential for optimal engine performance. Use specialized software or a tuner, such as SCT or H&S, to recalibrate the engine control module (ECM). This ensures the engine operates efficiently without the EGR system. Adjust fuel injection timing and turbocharger settings to compensate for the removal of exhaust gas recirculation. Improper calibration can lead to poor performance or engine issues. Always follow the tuner’s instructions and consider consulting a professional for precise adjustments. Ensure the engine runs smoothly and meets the desired performance benchmarks. Proper calibration also helps maintain reliability and prevents potential damage. Adhere to the manufacturer’s guidelines and torque specifications for all connections to guarantee a safe and effective setup.
5.2 Testing the System
After completing the EGR delete installation, thoroughly test the system to ensure proper functionality. Start the engine and listen for any unusual sounds or leaks. Check the exhaust system for leaks using soapy water or a smoke test. Monitor the engine’s performance and sensor readings using a diagnostic tool. Perform a test drive under various conditions to assess power delivery and responsiveness. Verify that all components are securely connected and functioning as intended; If issues arise, consult the installation manual or seek professional assistance to resolve them promptly. Proper testing ensures reliability and safety, confirming the success of the EGR delete modification.
Common Mistakes to Avoid
During Ford 6.7 EGR delete, avoid misaligning block-off plates and neglecting torque specs. These errors can cause leaks and engine damage. Use proper tools and follow instructions closely.
6.1 Incorrect Installation of Block-Off Plates
Incorrectly installing block-off plates can lead to leaks, reduced engine performance, and potential damage. Ensure plates are properly aligned with gaskets to maintain a tight seal. Avoid overtightening, as this can warp the manifold. Use the correct torque specifications for all bolts to prevent damage. If unsure, consult a professional or detailed instructions to ensure a proper seal and avoid costly repairs. Proper installation is critical for maintaining engine integrity and performance.
6.2 Ignoring Proper Torque Specifications
Ignoring proper torque specifications during EGR delete installation can lead to leaks, damage to threads, or even engine component failure. Always use a torque wrench and follow the manufacturer’s guidelines. For block-off plates, torque bolts to 15-20 ft-lbs, and for exhaust manifold bolts, 30-40 ft-lbs is typical. Refer to your kit’s instructions for exact specifications. Over-tightening can warp surfaces, while under-tightening may result in leaks. Proper torque ensures a secure, leak-free connection, preventing costly repairs and maintaining engine performance.
