By wrapping your headers with Exhaust Heat Shields Header Insulating Wrap, you keep exhaust heat in your pipes where it belongs. This reduces underhood temperatures up to 70 percent, and cools the incoming air/fuel mixture to increase horsepower and fuel efficiency. Not only that, but the reduced heat also extends the life of electronic components. Exhaust wrap can withstand continuous heat up to 2,000 degrees F, and installs easily with standard hose clamps or the optional stainless steel Snap Straps.
