To accurately measure NOx levels in your exhaust, NOx sensors have to be extremely sensitive. Unfortunately, this means they’re also quite delicate. The average NOx sensor should last for 50,000–60,000 miles, but many of them fail long before this! Most malfunctions are caused by soot build-up, but NOx sensors can also be contaminated by moisture […]
Better Coating, Better Performance.
Roadwarrior is the only manufacturer to use Metalcor® catalyst technology across its entire range of Diesel Oxidation Catalysts (DOCs) and Selective Catalytic Reduction catalysts (SCRs). Metalcor® catalysts feature high activity catalyst coatings fused to thinner, stronger, catalyst substrates to guarantee maximum performance under the harshest conditions.
Metalcor® catalyst coatings are designed and produced in our own labs. We then inspect each unit to ensure you get more fuel efficiency, lower consumption of DEF, and long term performance from your heavy duty engine!
