Lower your Subaru’s under-hood temperatures and protect exhaust components with the DEI Form-A-Shield Heat Barrier Sheet. This premium heat shield is designed to withstand direct heat up to 1400°F, making it ideal for exhaust headers, manifolds, turbo housings, and downpipes. Its pliable design allows it to conform to various shapes, ensuring a custom fit for your Subaru WRX, STI, BRZ/86, or other models.

Constructed from 10 mil dimpled aluminum bonded to a high-temperature basalt thermal barrier, Form-A-Shield effectively reduces radiant heat while maintaining durability against oil and chemical spills. It can be applied directly to hot surfaces without adhesive backing, fastening securely with straps, clamps, or DEI Locking Ties. For non-hot areas, DEI Adhesive Spray can be used for added heat reflection.

Perfect for Subaru enthusiasts looking to improve performance and protect engine bay components, this heat barrier sheet offers reliable thermal insulation and easy installation. Upgrade your exhaust heat management today—shop Form-A-Shield at Subimods.
