A system designed to remove the emissions control devices, such as the diesel particulate filter (DPF) and exhaust gas recirculation (EGR) valve, from a Jeep Gladiator equipped with an EcoDiesel engine is often referred to by this term. These kits typically include components to bypass or eliminate the factory emissions equipment, along with software modifications to prevent error codes and ensure proper engine operation.
The motivation behind eliminating these systems often stems from perceived improvements in engine performance, fuel economy, and reduced maintenance costs. Factory emissions systems can, under certain conditions, restrict airflow and contribute to issues like clogged filters, leading some owners to seek alternatives. However, it is critical to acknowledge that removing or tampering with these emissions control devices may violate federal, state, and local regulations regarding vehicle emissions, carrying significant legal and environmental ramifications.
