💡 What is an automotive heat shield and how does a reflective barrier work in high-temperature engine areas?

Here's a handy overview to help you decide how it helps. - Radiant heat is reflected away from critical components to keep temps down and protect wiring, hoses, and metal surfaces
- It reduces heat transfer to firewall, floor pans, and nearby engine bays for a cooler cabin
- The peel-and-stick design makes quick installation on clean surfaces straightforward
