Fits select 1997-2004 Jeep Cherokee, Grand Cherokee, and Wrangler models equipped with the 4.0L engine.

Protect your fuel system from underhood heat soak and vapor lock with the DEI Fuel Rail and Injector Cover Kit. Specifically engineered for the legendary Jeep 4.0L inline-six, this kit shields critical components from radiant heat rising from the exhaust manifold. This is especially vital for the #3 injector, a known problem area for heat-related fuel issues in Jeep engines.

The kit features an 8mm thick thermal barrier compressed between dual layers of heat-reflective aluminum. This construction is designed to withstand the high temperatures of off-road trail use and daily driving. The fuel rail and injector covers utilize high-temperature glass fiber with a reflective skin to keep fuel temperatures stable for consistent performance. Installation is straightforward using the integrated hook-and-loop closures, requiring no permanent modifications.
