HEAT PROTECTIVE SPARK PLUG BOOT SOCKS

Killed another set of plug wires. The heat from the headers is cooking the boots.
So I got some 1200 degree thermal "socks" for them.

These are the DEI (Design Engineering Inc) line. They are two layers of high temp fiberglass with an integrated metal ring to keep the sock down on the boot.

I got them from Summit, 51.95 $ p/n DEI010532. Available in other colors and lengths. Mine are 6 inch long.

there are other vendors and other similar products. Jegs also sells them.
