I have the Afe Pro 5R , which I really like , the sound & looks good , I don't think it's pulling in that much heat & that would be only when sitting still for a while , when moving it's getting ambient air just like stock box , but I think the stock air filter box is also good up to about 800 rwhp. I have the JLT hood vent shield on to hold in air & keep water out but it's not a DD so not a problem with me.
