So what will urea injection do in terms of cons/disadvantages?
We all know the woes of the dpf to help clean up emissions, however if and when urea injection is used...what will the negatives be? Less performance mods able to be used? etc etc. I don't know much about them.

I read you will have a urea tank that needs to be replenished periodically... which sucks.

Yeah I read that too, however it made it seem that it's a while before each fill. However does anyone know if there are any negative performance issues due to the urea injection? Or maybe some modifications that cannot be added anymore?

most likely every 3 to 5 tanks of fuel, you refill the urea tank. aftermarked tuners will have a hard time with all the emissions stuff going on the trucks..

Means ya gotta drink alot of water and it will piss ya off after a while :P
The injection shouldn't have a huge issue with performance add on's it is just going to be ballancing the performance stuff with the emissions stuff. I just hope that the DPF crap goes to hell cause talk about a completely idiotic setup IMO. |

based off of what i heard ....
the urea is injected into the exhaust system and therefore will not effect performance or mileage .... just what i heard and i haven't looked into this much .... |

How much per mile do you think the costs will be? I would think some tuners would make a "race" version to eliminate this.

I read about this already and from what it says, that it will get sprayed directly into the exhaust and that's about the just of it. But some people say it's going to cost alot per gallon because it is widely used for other things so it's going to drive the price up.

Believe you will get it refilled at oil changes. You can read up w/o much detail at BWM. They have it in their new diesels as does most people these days.
