   The 6.4 L also has a DPF and dual EGR coolers which are capable of reducing exhaust gas temps by up to 1,000 degrees before they reach the EGR valve and mix with the intake charge. The DPF traps soot and particulates from the exhaust and virtually eliminates the black smoke that most diesel engines expel upon acceleration .
