DEI Form-A-Shield is a direct-contact extreme heat barrier rated to 1400°F+ that can be applied straight to exhaust headers, manifolds, turbo housings and downpipes to cut radiant exhaust temperatures and lower under-hood heat. Built from 10mil dimpled aluminum bonded to a 1/4in basalt thermal-barrier mat, it is extremely pliable, resists oil and chemicals, and fastens with straps, clamps or DEI locking ties (no adhesive backing). This piece is 42in x 48in.
