Crown Automotive 4883385K Exhaust Manifold Kit for 91-99 Jeep Wrangler YJ & TJ, Cherokee XJ & Grand Cherokee ZJ with 4.0L 6 Cylinder Engine

As well engineered as Jeeps are, early model Wranglers and Cherokees have noticed that the factory exhaust manifold cracks at the same spot. Enter the Crown Automotive Exhaust Manifold Kit to solve the problem. Made of tubular steel and fully welded construction rather than the cast steel versions in the past, this header kit has expansion and flex potential at the point of known failure. This extra engineering makes it so the manifold can outlast its earlier cousin. This kit includes the manifold gasket at the head as well as the seal for the front pipe, and ports for oxygen sensors are welded in place to maintain your factory emissions controls.
