Keep your diesel's SCR aftertreatment dosing correctly with the Bosch Diesel Exhaust Fluid (DEF) Injection Nozzle 0444021036. It serves as a direct-fit replacement for the listed application — the 2014-2015 Chevrolet Cruze — sitting in the exhaust ahead of the SCR catalyst, where it meters diesel exhaust fluid into the hot exhaust stream. Once atomized, the DEF (a urea solution) converts to ammonia that reacts with nitrogen oxides across the SCR catalyst to help lower NOx emissions.
