Heatshield’s FR Shields are designed to wrap around the fuel-injector rails, deflecting engine heat and keeping the fuel rails and fuel inside them cooler, improving engine performance, reducing the risk of vapor lock and decreasing the likelihood of pre-ignition. The shield kits fit both single- and dual-rail systems and are engineered to withstand up to 1,100 degrees Fahrenheit of continuous heat and up to 2,000 degrees Fahrenheit of intermittent heat. Custom lengths and diameters are available.
