Yeah, if there's no way to run the intake out of the engine bay, the stock box is the best bet to keep intake temps down. Like you said, just modify it to optimize airflow. Definitely the K&N drop in filter and remove the flap, and maybe replace the stock intake tube with a smoother one that doesn't change size. Or ate least changes size in the right way(think speedstack).In all honesty, the factory airbox is really well designed and flows great with a few minor modifications and a decent panel filter.
Biggest issue is these cars run pig rich from the factory. It's a shame, because with a decent tune you could probably see significant gains from just afr tuning. The only company that even offers tuning for these cars will only sell you THEIR tuned PCM which makes it a bit cost prohibitive for what you actually get.
This is one of the biggest reasons I got rid of my car. So much potential, but so few options. Sad, because I really loved my Genesis.
