I like the mini ram air, but you are still going to be pulling hot air in from under the engine bay. You could box the filter up in an inclosure to isolate it from the heat and try to pull air in from outside the engine compartment....
this is a cold air setup that I have on my nissan:

Also, is the cone cotton (like K&N) or paper? If it is Cotton, it needs to be oil to trap dirt...
Nice setup though!
