OK. Personally I've felt that the engine bay was way too hot even with the OEM header and its heat shields.
I just installed a JDL 4-2-1 that I had ceramic coated and I wrapped to try and reduce engine bay temps. I also used the DEI heat tape on the entire intake tube and box and that definitely helped.
I would be worried about wrapping the coils because they do generate their own heat and I would worry about sealing in some of that heat too.
