Plug boots Burning TTI Headers

I've tried a few things, but so far what seems to be working is a combination of the MSD High Temp Racing boots along with the MSD Boot Guards. I have a boot that rest on the primary pipe, so it sees a LOT of heat.

MSD Ignition 3412 MSD Pro-Boot Guards | Summit Racing

They've held up good for the summer so far. If I have any issues, I might try those Pertronix boots mentioned above.
