hello, there are 2004 diesel Excursion, a diI would like to upgrade my excursion of emission 3 to issue 4 there is a DPF for the 2004 diesel Excursion buy diesel particulate filter there must be a way to reduce emissions, or I can drive my Excursion is no longer here in Germany, please help me

 

You might try searching for an add-on urea injection kit possibly. Adding a DPF wouldn't help much, because the trucks computer is not set up to go into a regen.

 

There was a company at SEMA doing retro fits of DPFs on 6.0s! I don't remember the name though. Let me do some research and get back to you
