This stud secures the exhaust manifold to the inlet manifold on Land Rover's 2.25 petrol engine, a configuration used on Series vehicles where both manifolds share a combined mounting arrangement on one side of the engine. Correct thread form and stud length are critical here - an incorrect or damaged stud can result in manifold gas leaks, loss of engine performance, and heat damage to surrounding components. Key Features Threaded stud designed specifically for the exhaust-to-inlet manifold joint on the 2.25 petrol engine Replacement is recommended any time the manifolds are removed, as heat cycling weakens studs over time Corresponds to OEM fitment specification for Series 2, 2A, and Series 3 applications Inspect associated nuts and manifold gaskets at the same time to ensure a reliable seal on reassembly Vehicle Fitment Fits Land Rover Series 2 and 2A with the 2.25 petrol engine, and Land Rover Series 3 with the 2.25 petrol engine, at the exhaust to inlet manifold joint.
