1. Buy a scan gauge and monitor intake air temps, water temps, and inverter coolant temps.
2. Block lower grill completely
3. Warm air intake from header area with a tube and hose clamps.
4. block upper grill
All vehicles usually have open engine bays that can be seen to a certain degree through the wheel wells. Plug them up and see what improvements it makes and how much you need to plug it up. Same thing for holes in the underbody cover of the engine bay.
