Hood clearance, big wrench in cog

I just bought a cheap drop base air cleaner off of e-bay, it was zinc coated with a filter for $25.
I put a much bigger filter on it and painted it black, and it does not hit the hood and there is room to spare.
I am happy with it, but the more I think about it, the more I want cold air, the under hood temp is very high due to the exhaust manifolds.
Currently my heater fan does not work, and I don't even need it.
