So AMS just stated they saw no change when divorcing the factory heat exchanger from the engine coolant.
My first thought was that they found no change due to their testing environment. I imagine if they did back to back dyno pulls they would find a decrease in IAT’s. But just idling the water temps would be the same due to the SC getting heat soaked from the engine?
Without knowing their baseline and testing procedures it seems like BS.
Also their coolant reservoir looks like ass.
