One of the major performance upgrades available for diesel engines is EGR and DPF deletes. These aftermarket kits remove factory-installed components that limit performance and fuel economy in diesel engines. Two of the most common delete kits are EGR deletes and DPF deletes.
EGR stands for exhaust gas recirculation, which is an engine system that reduces a vehicle’s nitrogen oxide exhaust emissions. While an EGR may limit the amount of exhaust released into the atmosphere, it actually increases the amount of soot in your engine. This lowers engine efficiency by up to 3%, resulting in a 3% increase in fuel consumption in order to maintain the same amount of power.
Other issues related to the EGR include sticky valves, leaky cylinders, cracked engine components and coolant problems just to name a few.
An EGR delete bypasses the system, making your truck run cooler, increasing the engine’s lifespan, and improving overall vehicle performance.
DPF stands for diesel particulate filter, which is a filter that captures and stores exhaust particulates (mostly carbon) in order to reduce diesel emissions. Unfortunately, the DPF also takes a major toll on your engine. In fact, a DPF can reduce your vehicle’s fuel economy by up to 30%!
As the DPF is a filter, it like all filters tends to get clogged over time. When this happens, you will notice a significant decrease in your vehicle’s already limited performance While you can clean the DPF, this is not always practical or affordable. In some cases, the DPF can get so clogged that it must be replaced all together. This alone can cost thousands of dollars. If left as is, a clogged DPF can cause significant engine damage.
Many drivers opt to install a DPF delete in order to increase horsepower, performance and torque. After installing these kits, drivers notice a major increase in power, fuel mileage, and engine lifespan.
