Heat Shroud AN Line 16AN x 10ft

The DESIGN ENGINEERING Heat Shroud AN Line 16AN x 10ft (SKU DSN10675) is a professional-grade hose and wire sleeve engineered to protect high-temperature fuel, oil, and coolant lines in performance and racing applications. Built from aluminized fiberglass fabric, this 10-foot heat shroud provides thermal protection for 16 AN hose runs while maintaining a clean, finished appearance under the hood.

The aluminized fiberglass construction reflects radiant heat away from sensitive hose lines, reducing the risk of degradation and failure in high-heat engine bays typical of turbo, supercharged, and naturally aspirated performance builds. At 10 feet in length, this sleeve accommodates extended fuel and coolant line runs from engine compartment through firewall transitions without requiring multiple spliced segments. The silver finish complements both classic and modern engine aesthetics while providing durability against oil residue, fuel contact, and vibration. At just 0.9 lbs, the sleeve adds negligible weight while delivering measurable thermal protection.

This product serves engine builders, performance technicians, and serious enthusiasts who run custom fuel systems, EFI conversions, or high-output engine combinations where heat management directly impacts hose longevity and system reliability. Fuel line degradation accelerates rapidly in proximity to turbo outlets, headers, and intake manifolds; a properly insulated 16 AN line can extend hose service life by years. The 16 AN sizing accommodates high-flow fuel delivery systems, nitrous feed lines, and large-diameter coolant circuits where standard hose protection is insufficient. Installation is straightforward—the sleeve slides over existing hose and secures with the included design or wrapping compatible with standard hose routing.
