I did the 6637 mod recently and love it but think i may need to make a heat sheild to go around it as it get warm/hot to touch after running the truck. Has anyone done this?
It is a high pressure oil crossover line that insures HP oil is the same on both heads. I just got a little throttle response. I am just doing stuff like that getting ready for the big mods, ie: injectors. That is where it helps most.
I made one out of metal laying around the house (click here). I sprayed it with some heat and noise bedliner type stuff that was like $8 for the can. Sure its not as nice as the afe but that system costs over 300 bones

IMHO you dont need it, I have read that the differences in temperature inside of the shield and in the motor compartment is not significative, and you also restrict a bit the air flow. just my .02 cents.
