Default Header Wrap question.

Header wrap is made to keep the heat under the hood down, but interm to that, how much more heat does it keep IN the motor, and how much hotter does it make the engine run? Is it worth it?

IMO Header wrap should only be used on off road only cars. or cars that will see no moister. They will keep water trapped against the headers making them rust out prematurely.

It will also void any warrenty on the headers. ZGo with ceramic coating it does the same thing and looks good too.

I'm in the header "biz".....
The major problem with header wrap is that it simply works too good. It does an excellent job of keeping the radiant heat in the header. There is one minor problem tho.... You "decarbonize" the metal at a faster rate, due to the higher temperatures retained in the tube, than if you did not have header wrap on the....header. the rapid loss of carbon in the metal makes the header more prone to vibration fractures & premature failure via fatigue of the hottest areas of the header tube. Steel tube becomes extremely brittle when it is decarbonized. As previously stated; all manufacturer's warranties are null & void once you use header wrap. The wrap itself permanently "stains" the header & is easy to spot..... So, there is no "sneaking" a warranty claim through....... IMHO
