It lowers combustion temps a lot, because there isn't as much oxygen.

For the blockoff plate setup, you don't need to do anything to the PCM because the EGR is still flowing air through, just not hot dirty air. If you completely remove the EGR system you will need some PCM work done or it will not be happy and you will get some of those lights on your dash lit up.

13secGTP is right, on ZZP it says you don't need to worry about the PCM at all with their blockoff plate. But what is ZZP'* plate? Just a piece of stainless steel?

Anyone else wanna jump in? I know jeffrey has a say, and what about you EGRless drivers?

I guess my concern is why the 92 bonnevilles keep burning out exhaust valves. Is it truly because they have no EGR system or something else?

Yup. I am not sure it is even stainless, but it may be. All it does is cover the hole where the EGR connects to the exhaust manifold, it doesn't have to be much. If you want a filter for the other end (which hopefully you do) you have to order it yourself, and it is something like $13. It is still a very nice setup, and keeps the engine nice and clean.

If I do this, I was thinking of just picking up a cheap APC oil line filter from Autozone. Why does ZZP sell a specific one?

I phrased that wrong. Why, (comma...let your mind pause for a moment) does ZZP sell one?

Ok screw that, DOES ZZP sell one?
