M1M EGR Cooler upgrade for Navistar Trucks equipped with Maxxforce 11/13 Engines – Engineered for Unmatched Thermal Durability

Imagine, the last EGR cooler you will need to buy for your truck. M1M™ EGR Coolers has invested many years in the development of a robust system that can take extreme thermal stresses created by modern, more fuel efficient engine designs.

Developed specifically for the Pro Star* truck’s heavy duty engine, our cooler replaces the high temperature side OEM insert with our proprietary flexible tube technology. Called “Bend-A-Flex”, our proven system is designed to withstand non-standard coolant events that can occur at any time.

No more EGR cooler failures due to the lack of coolant.

Tested for Reliability

Developed and tested in our leading-edge research facility located near Chicago, Illinois our Engineers repeatedly subjected our EGR cooler design to catastrophic cooling events and they came back for more.

Our Engineering capabilities include the following:

• Millions of miles of EGR Field data
• Stringently tested in our facilities for durability and OEM functionality
