This guy sells quality heat shield products at a decent price. I've got it all over my engine compartment on fluid lines and sparkplug boots. Some of the sparkplug boots are squished between the header pipe and inner fender - no burn through.

I used this on the fluid lines. You can tuck the ends under like spark plug boots or buy some of his high temp heat shrink tubing. -
