Cool-Tape 1 1/2in x 30'Roll

The Cool-Tape 1 1/2in x 30' Roll from Design Engineering is a professional-grade heat barrier tape engineered for engine bay and exhaust heat management in automotive applications. As a mechanic who works with high-performance builds, modified engine bays, and turbo installations, I can confirm this tape addresses a critical problem: uncontrolled radiant heat that degrades hoses, wiring, and nearby components. This reflective tape is essential for custom builds where routing constraints force fuel lines, electrical harnesses, or plastic components near hot exhaust manifolds, headers, or turbochargers.

Design Engineering's Cool-Tape works by reflecting infrared radiation away from protected surfaces rather than merely insulating them—a more effective approach for tight engine compartments. The 1 1/2-inch width makes it ideal for wrapping fuel injector lines, vacuum hoses, and wiring looms in confined spaces where bulkier wrap would create installation headaches. At 30 feet per roll, you'll have enough coverage for most single-engine fuel systems or multiple auxiliary lines in a typical modification project. The tape's pressure-sensitive adhesive bonds reliably even in engine heat cycles, and the reflective surface resists UV degradation better than standard electrical tape or cheap heat wrap alternatives I've seen fail within a season.

Anyone running a fuel-injected engine with custom headers, a turbo upgrade, or relocated components benefits from this tape's protection. It's particularly valuable in supercharged or turbocharged builds where underhood temperatures exceed 180°F in proximity to fuel system plumbing. Installation is straightforward—simply wrap it around hoses or lay it as a barrier between heat sources and sensitive components, pressing firmly for adhesion. This tape pairs well with ceramic exhaust wrap for headers or manifolds but works independently for targeted protection of individual lines. For road-race or street-performance applications, it's an inexpensive insurance policy against fuel line degradation, vapor lock conditions, and electrical harness failure caused by radiant engine heat.
