Wiring harness connectors and AN fittings sit dangerously close to exhaust, turbos, and other heat sources in modern performance engines. The Heatshield Products Utili-Shield Lava wraps those plugs and junctions in rugged volcanic rock fiber, rated to 1200°F continuous and 2000°F intermittent, so heat-induced brittleness and connector failure stay off your radar.
Volcanic rock construction outperforms fiberglass. Lava rock fibers deliver 25 percent greater strength than fiberglass while resisting abrasion, oil, chemicals, and acids. That combination keeps the shield intact and protective across the full duty cycle, even in the harshest underhood environments.
Fits tee and 90-degree configurations. Available in tee and 90-degree versions across four inside-diameter sizes: 1/2-inch, 3/4-inch, 1-inch, and 1-1/2-inch. The geometry matches common harness plug shapes and AN or fluid-line connectors without requiring custom fabrication or modification.
No disassembly required. A high-temperature hook-and-loop fastening system lets you install the shield directly over existing connectors and fittings in minutes, without pulling apart the harness or disconnecting lines. Beyond wiring protection, the same shield covers AN and fluid-line fittings to help prevent vapor lock and keep oil lines cooler under sustained heat exposure.
