Volvo 23920469 Secondary Fuel Filter — D11, D13 Engines

The 23920469 is a secondary fuel filter engineered for Volvo D11 and D13 heavy-duty diesel engines. Positioned downstream in the fuel system, it provides a critical final stage of filtration — removing microscopic contaminants and trace water before fuel reaches the high-pressure common rail injection system. Key Features 99.9% filtration efficiency at 4 microns (ISO 2942 standard) Spin-on design with M32 × 1.5 thread for fast, leak-free replacement 250 psi collapse/burst rating for reliable performance under pressure 4.23" outer diameter — direct dimensional match for OEM housing Protect Your Injection System Modern common rail diesel injectors operate at pressures exceeding 30,000 psi with tolerances measured in microns. Even trace amounts of contamination can cause injector scoring, poor spray patterns, and costly failures. This filter is your last line of defense, ensuring only ultra-clean fuel reaches these precision components. Vehicle Compatibility Designed for Volvo VNL, VNR, and VHD trucks equipped with D11 and D13 engines. Pairs with the primary fuel filter for complete system protection.
