Hey all,

Anyone have experience with the vrp heat exchanger or split cooling kit on their E63? Notice any increased performance in higher temps?

Members that installed "upgraded" HE of various brands reported they didn't do a thing for them. I believe it was a thread about the CFS HE if I am not mistaken.

For a 2016 you would be upgrading both of the side units, Upgrade the Pump alongside with them. HEs alone with the slow flowing factory pump wont make a massive difference, but pairing that with a pump will do alot.

I have the Pierburg pump, AMS Aux HE, CFS front HE, and the always-on pump mod. The only one that did anything to reduce IATs was the pump mod.
