TEGIWA Heat Wrap. This titanium wrap is designed to manage engine bay temperatures. This is the best type available and is made from titanium fibre. This makes it tougher and more durable than all other types. This withstands heat better than conventional wrap. The wrap is wound around the manifold and exhaust to reduce heat radiation. The exhaust tubing becomes hotter which speeds the gas flow. The under bonnet temperatures are reduced which gives a cooler denser intake charge. The wrap can also be used to keep heat from unprotected critical engine bay parts (master cylinders, alternators etc).
