Flexible Heat Shield 3.5 in x 6.5in Brushed/Onyx

The Flexible Heat Shield 3.5 in x 6.5 in Brushed/Onyx from Design Engineering is an essential thermal barrier for serious automotive builders and mechanics working on high-heat engine compartments. This product is designed to absorb and reflect radiant heat away from temperature-sensitive components, making it ideal for applications such as routing exhaust lines near fuel injectors or protecting brake lines from turbo chargers.

Constructed with a fiberglass-reinforced material and a reflective backing, this heat shield can handle extreme underhood temperatures while maintaining flexibility for custom routing. Its unique design allows it to wrap, bend, and conform around irregular shapes without cracking or separating, unlike rigid aluminum shields. The brushed onyx finish not only resists glare but also maintains a clean, professional appearance.

Whether you're a professional mechanic or a weekend warrior, this heat shield provides substantial coverage for localized protection, ensuring that critical components remain safe from heat-related failures during aggressive driving or forced induction builds. Its minimal weight of 0.33 lbs keeps underhood weight gains negligible, making it a practical choice for restoration or performance upgrades.
