that is a big core!
the other alternatives I would suggest are, as long as you're not running the factory airbox & resonator on the passenger side:
1. passenger side, flat mount with a hole cut out of the under tray, ducting from the front bar down onto the core;
2. passenger side, cut out inner guard and fit core in the cut out, duct from the front bar cut out to the core;
Both ways you are forcing clean cool air over the core.
Make sure that, as beer baron eluded, that you allow an exit to the airflow - if you don't the core will be pretty much useless.
