Make sure that there's no expensive electronics with heat-sinks that will be starved for cooling air hiding in there.
My Toyota has the ignition igniter module attached to the passenger side inner fender well underneath the airbox, which receives some airflow leakage around the radiator bulkhead. It's spaced off the surface for air circulation. It's full of circuit board. Perhaps some transistors or diodes which require air-cooling.
You'll want as much money for mods as you can, rather than replacement parts for 'cooked' components.
