Mack CHU Fuel and Emissions Systems

Carquest Premium Diesel Exhaust Fluid (DEF) Filters help reduce harmful emissions and improve air quality. DEF filters remove impurities such as dirt, debris, and particulates from the diesel exhaust fluid before entering your vehicle’s emission control system. These filters allow clean fluid to break down harmful nitrogen oxide (NOx) gases produced during diesel combustion. By ensuring proper DEF flow and helping protect system components, DEF filters help diesel engines meet strict emission standards. Carquest Premium Diesel Exhaust Fluid (DEF) Filters are designed to meet or exceed the performance requirements of the Original Equipment Manufacturer (OEM).

Product Features:

• Designed to meet or exceed OE filter performance levels over the entire OE recommended service interval.
• Contains Plug and Filter Removal Tool
