Ideas for tackling turbo heat?

[Y-TRY]

What are some ideas and solutions for battling underhood heat from turbos? It gets extremely hot in there, and the paint on the fendeers won't last long with this heat.

Do you shield the heat source, like the turbo heat shields that are available? Do those work? Or do you shield everything else?

I was thinking about building "halo" heat shields around my intake pipe since it gets heated in there. Similar to what you see on the Mule, where the pipes run close to the downpipes. Basically another tube around the existing one, about 1/4" space all around, if I have that much room. But I'm not sure how effective it will be.

What have you guys seen or done that works? What are you planning on doing?
Any brainstorming will be appreciated
