Header Wrap/ High Heat Coating
Header wraps help increase exhaust savaging and horsepower, but also lower underhood temps, including heat deflection to the radiator. Thermo-Tec exhaust wraps withstand continuous heat-up to 2,000F-and are engineered from textured, silica-based fabric with a patented inorganic coating. Using the Thermo Tec Hi-Heat Coating spray and Snap Straps will protect the wrap from fraying and harmful liquid spills. Recently tested by 2NR, we found the Thermo-Tec wrap helped decrease coolant temperatures by a whopping 39.2 degrees Fahrenheit on our project STI when driving around town.
Standard radiator hoses are made with plies of polyester able to withstand a max temp of 356 degrees Fahrenheit, and can deteriorate from extreme coolant temperatures and chemicals. Samco Sport silicone hoses are individually hand crafted with an Aramid lining (for turbo applications), suitable for temperatures up to 482 degrees Fahrenheit.
