so I wedged in a heatshield for my new build. I am doing light cruising and idling mostly with my new haltech setup. When I touched the intake manifold, it was burning hot. Ambient is around 50-60*F, so I think it's because the heatshield is now acting as a conductor rather than a shield... the shield is touching the exhaust and the manifold. It's made of SS on exhaust side and I covered the exposed insulation on the backside with aluminum tapes. Is there something I can use as heat shield that will hug the UIM tightly, not directly conduct heat, and be an effective shield for my application?

 

This should sort you out...or at least give you an idea.
