DEI Reflect-A-Cool 3ft x 4ft Sheet

If you're working on a custom exhaust setup or trying to keep heat away from sensitive components under the hood, DEI's Reflect-A-Cool sheet can be a real lifesaver. This material is designed to block radiant heat, which is especially useful in tight engine bays or race car applications where you can't always get a lot of space between heat sources and things like wiring, hoses, or fuel lines.

It's made from a fiberglass material with an aluminized foil layer that can handle direct, continuous temperatures up to 400°F, and it's rated to protect against radiant heat up to 2000°F. The best part is how easy it is to install – you just measure, trim it to the shape you need, peel off the backing, and stick it on. It's moisture and solvent resistant, and because it's so thin and flexible, you can get it into just about any spot. Just remember, it's meant for shielding from radiant heat, not for direct contact with exhaust pipes themselves.
