Cummins ISL DOC

Breathe New Life into Your System: Cummins ISL DOC Replacement

What is it?
The Cummins ISL Diesel Oxidation Catalyst (DOC) is an essential component in your engine’s aftertreatment system. It works by converting harmful exhaust gases—like hydrocarbons and carbon monoxide—into less harmful compounds before they reach the Diesel Particulate Filter (DPF). This helps maintain clean exhaust flow and supports consistent regeneration cycles.

Whether you're experiencing failed regens, increased fuel consumption, or diagnostic fault codes, replacing the DOC can restore balance and flow to your emissions system.
