Form-A-Shield™ solves the problem of needing a direct contact, extreme heat barrier.

Capable of withstanding direct heat of up to 1400°F+, Form-A-Shield™ was designed to provide the best possible heat protection in areas where high temperatures are always present and problematic. Form-A-Shield™ can be applied to exhaust headers, manifolds, turbo housings, and downpipes to dramatically reduce radiant exhaust temperatures.

Ideal for firewalls, exhaust manifolds, under-vehicle, floor pans, oil tank box areas, transmission tunnels, wrapping fuel cells, under hoods & more.

Formed from 10 mil dimpled aluminum, bonded to a high temperature rated basalt thermal barrier material, Form-A-Shield™ can be applied directly to hot surfaces helping to lower under hood temperatures while keeping more heat in the exhaust system.

NOTE: Use DEI Adhesive with Form-A-Shield on non-hot areas to serve as a heat barrier / reflector.
