All of it. Allows more airflow, therefore more cooling. He also removed the heater valve; coolant flows through the core full time. I was initially concerned about this but Mike has run this config before without issue. The Toy heater design directs outside air either over the core or bypasses it. No unwanted heat at all so far.

This solved an issue with heater hose routing, where a 180* turn in very tight quarters was required to keep the valve. Much cleaner without it.
