Detroit Diesel A4711800209 Oil Filter — DD13 DD15 DD16 (2020+)

The A4711800209 is a genuine-specification engine oil cartridge filter engineered for the Gen 5 Detroit Diesel DD13, DD15, and DD16 platforms (2020 and newer). As the primary full-flow filter, it captures metal particles, carbon, and combustion byproducts before they can damage bearings, the turbocharger, and the valvetrain — critical protection across the long service intervals modern Detroit engines are built for.

Key Features

• Direct replacement for Detroit Diesel A4711800209 (supersedes A4711800009)
• OE-grade synthetic cellulose media captures particles down to 15 microns
• Robust steel housing with anti-drainback valve for rapid cold-start oil pressure
• Designed for extended Detroit drain intervals (typically 35,000–50,000 mi depending on duty cycle)
• Kit includes fresh O-rings and housing seals for a leak-free service

Why It Matters

Detroit DD-series engines use precision turbocharger bearings, variable-geometry vanes, and tight main-bearing clearances that are intolerant of contaminated oil. Running a worn or off-spec oil filter allows abrasive particles to circulate, causing accelerated bearing wear, turbo failure, and eventual loss of oil pressure. The A4711800209 maintains OEM-level filtration efficiency throughout its full service interval, protecting the engine investment and keeping the truck on the road.

Vehicle Compatibility

Direct fit for Freightliner Cascadia (PT-126, 2020+), Western Star 5700XE, 49X, and 57X trucks equipped with Detroit DD13, DD15, or DD16 engines. Also replaces a wide range of Mercedes-Benz OEM numbers used on related Actros/Antos platforms — A4731800509, A4731800809, and the A4721842xxx supersession family.
