Default Heat insulation for engine wires

Do you guys think it would be a good idea to redo all my engine wires with this stuff? I have a top mount twin turbo setup on my car and it generates a lot of heat. BTW, I don't mean the spark plug wires.

OH! Do you have anyway to reroute them away from your hot pipes? That insulwire stuff should work fine but I would really just try to get them away from the hot parts.

The problem is that anywhere under the hood with this setup is a hot spot lol. I'm just trying to find a way to protect the wires best. All the plastic loom melted.

I wrapped my main harness with header wrap insulation. I am a little over 100,000 miles now and did need to replace one coil harness around 60,000 because it was crunchy. I also have a button type eletric sensor that closes at 200F that is mounted high on my firewall that turns on my radiator fan if the underhood temp is over 200f, it comes on in the summer about 5 minutes after you park it and runs about a minute.

I was thinking about using header wrap and decided to go with the Russell's instead. My concern is that it won't hold up.
