DPF & Additive System – Replacement Diesel Particulate Filter Additive Components

Shop replacement DPF additive tank units and related diesel emission-control components at Shop4AllParts. Explore vehicle-specific replacement parts for compatible diesel cars, SUVs, vans and commercial vehicles.

A diesel particulate filter (DPF) captures soot particles from engine exhaust gases. During regeneration, accumulated soot is burned off under controlled conditions to help maintain the filter's operation.

Certain diesel vehicles use a dedicated fuel-borne additive system to assist DPF regeneration. Depending on the vehicle design, this system may include an additive reservoir, pump, dosing components, sensors and electronic controls.

Our current collection includes replacement additive tank units for diesel particulate filter systems.
