Wrapping can significantly decrease underhood temperature by up to 45% or more. Promotes a cooler denser intake charge and avoids premature failure on costly engine components due to thermal deterioration. also increases exhaust gas velocity and increases horsepower. Constructed of a high temp resistant woven fiberglass that is then pre-heat stressed in a process called burnishing. A vermiculite coating is then applied to act as a bonding agent and to increase durability levels under extreme heat - up to 2000ú F.
