The 6.4L Power Stroke diesel engine, used in Super Duty trucks from 2007-2010, is a powerful workhorse but its factory Exhaust Gas Recirculation (EGR) system has been known to cause issues over time. The EGR setup is meant to lower NOx emissions but ends up contributing to a buildup of carbon deposits that can cause symptoms like stalling and smoking. An EGR delete kit provides a simple solution by removing flawed EGR components and installing a block-off plate in their place.
Not only does this eliminate problematic stalling and sludge formation, it allows the 6.4L engine to breathe more freely—resulting in significant gains to both horsepower and fuel economy. An EGR delete also reduces particulate emissions by improving combustion. Join us as we explore the benefits of increasing your 6.4L Power Stroke performance through a 6.4 egr delete kit.
What is the EGR system?
The Exhaust Gas Recirculation (EGR) system is utilized in diesel engines to lower nitrogen oxide (NOx) emissions from the exhaust. With EGR, a small amount of exhaust gas is vented back into the intake manifold where it gets mixed with fresh air entering the engine. As the exhaust gases contain little to no oxygen, their introduction decreases the combustion temperature inside the cylinder.
Lower peak combustion temperatures mean fewer NOx molecules are formed, allowing the engine to meet stringent EPA emissions standards. However, issues can develop over time as the recirculated exhaust gas condenses and forms carbon deposits that clog valves and ports in the EGR system.
Product Overview
The 6.4L Power Stroke EGR delete kit provides all the necessary components to remove the factory Exhaust Gas Recirculation system. Included is a precision-machined aluminum block-off plate that mounts in place of the EGR valve and attached pipes. Stainless steel fasteners and gaskets are also supplied to ensure a durable seal.
The 6.4 egr delete kit is designed to plug the vacated EGR port while maintaining the engine layout. Customers will also receive instructions detailing the simple half-day installation process. Most importantly, the use of the 6.4 egr delete kit requires a dealer-installed tune to optimize engine performance without EGR functionality playing a role.
Benefits of an EGR delete kit
- Increased horsepower – Removing the restrictive EGR system allows for more efficient airflow into the engine, resulting in notable horsepower gains throughout the rpm range. Installing a 6.4 egr delete kit eliminates the EGR system’s airflow restrictions, freeing up the engine to breathe easier and produce more power at all engine speeds.
- Improved fuel economy – A cleaner combustion process without excess burned gases means unscrubbed fuel can be burned more completely, enhancing miles per gallon.
- Reduced carbon buildup – Eliminates the major source of sludge formation in the intake and on valves/pistons from reintroduced emissions.
- Smoother operation – No more stalling or hesitation issues associated with EGR failures or restrictions to airflow.
- Less smoke from exhaust – Deleted EGR components cannot malfunction and cause white clouds out the tailpipe.
- Longer engine life – Removing a fault-prone system enhances reliability and avoids expensive repairs down the road.
- Improved drivability – The engine responds better without lag from the EGR recycling burned gases.
- Simple installation – Replacing EGR parts with a plug-and-play block-off plate takes just hours with basic tools.
Installation of EGR Delete Kit
Installing an EGR delete kit is a straightforward process that most mechanics can complete in just a few hours. The first step is to drain the engine coolant and disconnect the battery for safety. Next, detach any wires or hoses connected to the EGR valve. Using basic hand tools, unbolt the EGR valve and associated piping from the engine.
Clean any residual gaskets or sealant from mounting surfaces. Then, apply a light coating of silicone to the included block-off plate gasket. Bolt the plate into position where the EGR valve was previously located. Reattach any disconnected lines and refill the cooling system. Start the engine to check for leaks before taking it out for a tune.
Emission Reduction
While EGR systems are intended to lower NOx emissions, removing a faulty EGR unit from a 6.4L Power Stroke can reduce overall exhaust particulates. As the EGR introduces aged exhaust gases back into the combustion chamber, it increases the amount of partially burned fuel entering the exhaust.
An EGR delete allows for more optimized fuel injection and ignition timing through professional tuning. This results in cleaner, more complete combustion that emits fewer overall hydrocarbons and soot particles. With the EGR system bypassed, the engine can utilize a more fuel-efficient air-fuel ratio and reduce emissions in the process.
Conclusion
An EGR delete kit provides an effective way for 6.4L Power Stroke owners to rid themselves of problematic stalling and smoking issues, while simultaneously gaining noticeable horsepower and torque. By removing faulty EGR components and optimizing the engine tune, emissions are reduced through more complete fuel combustion as well.
Drivers will appreciate the improved throttle response and reliability without worrying about carbon buildup or expensive EGR repairs down the road. If you want to maximize your 6.4L Super Duty’s performance potential and reduce trips to the repair shop, an EGR delete kit installation is a smart choice.
