The Detroit Diesel DEF Filter Kit (A000 470 08 92) maintains the cleanliness of the diesel exhaust fluid system in Freightliner Cascadia trucks with DD13 and DD15 engines. Contaminated DEF can damage the SCR catalyst and dosing unit — components that cost thousands of dollars to replace. This genuine Detroit Diesel kit includes all components for a complete DEF filter service, including a removal tool to prevent damage to the DEF pump during filter extraction.

Q: Which trucks does this DEF filter kit fit?
A: Fits Freightliner Cascadia trucks with Detroit Diesel DD13 and DD15 engines. Genuine part A0004700892.

Q: How often should the DEF filter be replaced?
A: Replace at manufacturer-recommended service intervals, typically every 150,000–200,000 miles, or when DEF system fault codes appear.

Q: What is included in this DEF filter kit?
A: Includes the DEF filter element, housing seals, and a removal tool to safely extract the filter without damaging the DEF pump.

Q: Is this a genuine Detroit Diesel part?
