I created a heat blanket for the underside of my airbox by using a cardboard template, and then transfering it onto some heat shield material I picked up from Home Depot. (Yes I do alot of shopping there) I have noticed a huge difference in the heat reduction of the air box. As for HP #s, I couldnt tell you, but cooler air=better mixture. If anyone is interested, let me know, and I can post some pics and detailed instructions. I still say we need a How to Forum added on here.
