This aftermarket modification refers to a collection of components designed to remove or bypass elements of the emissions control system on certain 2015 Ram 1500 EcoDiesel trucks. These systems typically include the Diesel Particulate Filter (DPF), Exhaust Gas Recirculation (EGR) valve, and Diesel Exhaust Fluid (DEF) system. For example, such a kit might contain a replacement downpipe, a block-off plate for the EGR valve, and a device to electronically simulate sensor readings to prevent error codes.
The primary motivations behind employing this type of modification often stem from desires to improve fuel economy, increase horsepower, and reduce maintenance requirements. The stock emissions equipment can, in some instances, negatively impact engine performance and necessitate costly repairs. Historically, the implementation of these kits has been driven by individuals seeking to optimize their vehicle’s capabilities outside of regulatory constraints, prioritizing factors like enhanced power and reduced operational expenses.
