Design Engineering, Inc. (DEI) now offers a thermal Fuel Rail and Injector Cover kit designed to custom fit 1997-2004 Jeeps® equipped with an inline-six engine (L6). Jeep Wranglers and Cherokees often are at risk of heat-related fuel system problems that can cause rough idle or slow starting. DEI's fuel rail and injector cover kit reduce rail and injector fuel temperatures; reducing instances of vapor lock. With thermal protection from radiant or direct engine heat, injectors will perform more efficiently with more consistent throttle response. The kit includes: one manifold heat shield, 1 fuel rail heat cover, 6 fuel injector covers, and 12 fuel injector replacement O-rings. Both the heat shield and the fuel injector covers are made of high-temperature rated glass fiber material bonded to a heat reflective aluminized material. The fuel injector heat covers can be used for either stock or aftermarket fuel injectors. Easy to install, the injector covers feature a split design and sewn-in hook and loop fastening edge that takes only moments to install.
