Useful Information

Description and Purpose:

The Cummins® DOC Inlet Catalyst Module (4353326) is designed to begin the oxidation process of exhaust gases, effectively reducing harmful emissions prior to reaching the Diesel Particulate Filter. Aligned with EPA10 regulations, it is essential for emission control and boosting overall engine performance.

Why Replacement is Important:

Over time, catalyst modules can become less efficient due to the buildup of soot and other contaminants. Installing a new unit restores optimal exhaust flow, supports effective emission control, prevents excess backpressure, and helps keep the vehicle in compliance with environmental regulations—reducing the chance of penalties or unplanned service interruptions.

Impact on Vehicle Performance:

A well-functioning DOC catalyst module enhances exhaust flow and reduces toxic emissions, leading to improved engine responsiveness and fuel efficiency. It also protects vital components like the Diesel Particulate Filter and turbocharger, increasing overall system reliability and helping to prolong the engine’s operational lifespan.

Manufacturer Information:

Cummins® is a globally respected manufacturer of engines and emissions technologies, known for delivering durable and dependable components. With a strong emphasis on innovation and environmental responsibility, Cummins® is a preferred partner for OEMs and fleets seeking reliable performance and efficiency in even the most demanding conditions.
