Cool Cover GOLD from Design Engineering Inc. solves the problem of heat soak into air tubes and cold air intakes. High-temperature metalized polyimide lamination, bonded to a robust 20-ounce heat-treated glass-fiber-base material, Cool Cover GOLD will reflect radiant heat from air tubes and promote cooler, denser, more powerful air charge. With a unique full-length hook and loop closure design, Cool Cover GOLD can be installed and removed in seconds. Cool Cover Gold fits tubing up to 4 inches in diameter, and measures 28 inches in length. $86.
