Does def really work?

Most trucks built after 2010 require DEF, but it actually allows your engine to be more powerful while spewing out virtually no NOx. The heat from the exhaust converts the DEF into ammonia. The ammonia, mixed with exhaust gases, reaches the SCR. The NOx emissions are broken down.
