The DEI Form-A-Shield (12in x 21in) is the definitive solution for managing extreme radiant heat in high-performance automotive applications. Engineered for direct contact, this thermal barrier is essential for anyone looking to protect sensitive components from the intense heat generated by exhaust headers, manifolds, turbo housings, and downpipes.

Technical Specifications & Benefits

  • High-Temperature Rating: Withstands direct heat up to 1400°F+.
  • Advanced Construction: Features a 10 mil dimpled aluminum surface bonded to a high-temp basalt thermal barrier.
  • Extreme Versatility: Highly pliable material that easily conforms to complex shapes and tight configurations.
  • Chemical Resistance: Durable design that resists oil, fuel, and chemical spills.
  • Easy Installation: Can be fastened securely using straps or clamps for a permanent, reliable fit.

By effectively keeping heat contained within the exhaust system, Form-A-Shield significantly lowers under-hood temperatures and prevents heat soak in critical engine components.
