Clogged or degraded Diesel Particulate Filters (DPFs) can increase backpressure, reduce fuel efficiency, and even trigger forced regenerations—making the OEM 20R8020 filter a critical solution. Precisely engineered to meet Caterpillar’s original specifications, this genuine replacement ensures optimal filtration of soot and particulates, safeguarding your aftertreatment system’s integrity.
-
Reliable Soot Capture
The OEM 20R8020 DPF traps particulate matter efficiently, helping to prevent contamination further downstream in your aftertreatment system. A clean filter supports smoother combustion and protects downstream components from excess soot exposure. -
Supports Optimal Regeneration
Proper regeneration requires the right exhaust temperature and flow. A new OEM filter promotes consistent gas flow and helps maintain required thermal profiles, reducing instances of incomplete or uncontrolled regen cycles. -
Reduces Backpressure and Improves Fuel Efficiency
Over time, clogged DPFs increase exhaust backpressure—forcing the engine to work harder. Swapping in a new OEM filter with clean flow characteristics helps reduce drag, potentially improving fuel economy and engine responsiveness. -
One-Year / One-Million-Mile Warranty and Straightforward Replacement
Backed by a robust warranty, the OEM 20R8020 offers both long-term reliability and peace of mind. Its direct-fit design ensures hassle-free replacement with minimal downtime. -
Streamlined Core Return for Ease and Savings
The core charge system is designed to be simple—return the old DPF within the allotted time frame, and your deposit is refunded promptly, keeping servicing efficient and cost-effective.
Maintaining clean exhaust flow is essential not just for emissions compliance, but for the health of the entire aftertreatment system. When your DPF is due for replacement, the OEM 20R8020 offers an exact-fit, durable solution engineered to uphold performance—mile after mile.
