The Dorman Exhaust Manifold Kit is designed for Jeep Grand Cherokee and Wrangler models with a 4.0L 6Cyl engine, manufactured between 1991 and 1999. This direct replacement exhaust manifold is made of stainless steel material and includes all the necessary components for installation. The part is 48-State Legal, excluding California and New York, and comes in a kit quantity. The interchange part numbers include J960708 and 662691, making it compatible with various Jeep models such as Comanche, Grand Cherokee, TJ, and more.
The way dorman packages these, there is no protection for the gaskets. When I received mine the Intake/Exhaust gasket was wrecked from being smashed by the header itself moving around in the box. Be prepared to buy a new gasket. Also the welds are not pretty, I didn't expect them to look like a SEMA build, but I also didn't expect to have to grind some of them away inside the exhaust ports. A few of them were protruding far enough into the flow area that they could potentially inhibit smooth flow of the exhaust gasses. Again be prepared to do a bit of work before just slapping this on your engine. Fit is nice. It does what it's supposed to. Quality control at the factory could be a little tighter.
