reduce underhood temperatures by 70%
withstands heat up to 2000 f

Thermo-tech introduced the original exhaust insulating wrap in 1988. Since then, more than 2,000,000 rolls have been sold. The wrap helps increase horsepower and fuel efficiency by keeping exhaust gasses hotter for faster exiting velocity and intake temperatures cooler. Proprietary thermal conduction technology coating conducts heat across the wrap 's .063 thick surface, controlling heat buildup and dissipation. Lower underhood temperatures also increase engine and electronic-system longevity. 1 wide and 50 ' long.
