What is the difference between these two other than one flows through and one does not? Also is it possible to replace the one that doesn't flow through with the one that does later ? I have the one that does not is why .thank you This is mine .
The flow through plate is just a spacer and can be added anytime after the fact or during the initial installation. The EGR has both the secondary and primary cooling systems running through it. That plate is for the primary cooling system to flow through as if it were still flowing through the EGR. It is said that the pass through lowers coolant temps 5 to 10 degrees.
The brass fitting to the left of the red plate is for the secondary cooling system and allows the coolant to flow without entering the, then nonexistent, EGR. The shop here says they recommend No Limit plates, and they offer a pass through. They also said it didn't matter. For the little extra, it might be worth it to have the coolant flowing the way it did before the EGR removal.

Great explanation. I was hoping UGA33 will chime in as well.
