1in x 50' Black Header Wrap

The 1in x 50' Black Header Wrap from THERMO-TEC is purpose-built for engine builders, performance mechanics, and hot rodders who demand thermal management without compromising under-hood aesthetics. This wrap serves as a critical thermal barrier around exhaust headers, protecting engine bays from destructive radiant heat while keeping vital components—fuel lines, wiring harnesses, and intake manifolds—at safe operating temperatures. Whether you're running a naturally aspirated build, turbocharged application, or street performance engine, header wrap reduces underhood ambient temperature, improves air intake density, and extends the service life of surrounding components that would otherwise degrade under extreme thermal stress.

Engineered from high-temperature fiberglass composite material rated for sustained exhaust temperatures, the 1in x 50' Black Header Wrap features a woven construction that withstands direct contact with headers running 1200°F or higher. The 1-inch width provides optimal coverage density when spiral-wrapped around primary and secondary header tubes, while the 50-foot length accommodates most full-size V8 applications or multiple smaller-displacement builds. The black exterior finish resists UV degradation and maintains a professional appearance in any engine bay. Installation requires only a ratchet strap or stainless steel tie-downs; the wrap self-adheres under the tension method, requiring no adhesives or fasteners that might fail under thermal cycling.

This header wrap is ideal for street cars, race engines, restorations, and performance builds where thermal management directly impacts reliability and component longevity. Domestic V8 applications—including big-block Chevy, small-block Chevy, Ford, and Mopar engines—benefit most, though universal compatibility makes it suitable for any header configuration using 1-inch or smaller primary tubes. Professional installers and DIY enthusiasts appreciate the straightforward spiral-wrap method, which requires no special tools beyond basic tie-downs. The 1.06 lb weight per roll is easily managed during installation, and the compact 7.25 x 1.45 x 8.5 inch packaging fits any workbench or toolbox for on-site or shop applications.
