The Selective Catalytic Reduction (SCR) filter is a key part of the emissions control system on Cummins X15 engines from 2018 to 2023. Working within the SCR system, the SCR filter helps reduce nitrogen oxide (NOx) pollutants in the exhaust, supporting cleaner emissions and helping your engine meet environmental standards. When the SCR filter becomes restricted or worn, emissions performance and exhaust flow can suffer. The Cummins X15 SCR Filter OEM 5418549 from Tamerx Diesel Parts is engineered to meet original equipment standards, providing a dependable replacement to keep your emissions system functioning as designed.
