ACDelco Diesel Exhaust Fluid Injectors
ACDelco offers diesel exhaust fluid injectors for a wide range of Chevy and GMC vehicles. These parts are used to reduce pollution, injecting small quantities of diesel exhaust fluid (DEF) into the exhaust upstream of a catalyst, where it vaporizes and decomposes to form ammonia and carbon dioxide. The injectors are manufactured to meet or exceed OE fit and performance. Order the model recommended for your application.
