Land Rover Part Number: ERR7393 - Left-Hand Exhaust Manifold
ERR7393 is a left-hand exhaust manifold that routes exhaust gases from the left-hand bank of cylinders into the vehicle exhaust system on EFI 3.5L and EFI 3.9L engines. Fabricated to match the cylinder head ports, the manifold forms a flanged connection that mates to the downpipe and downstream components; correct sealing at the manifold flange and head face prevents exhaust gas leakage and helps maintain the back-pressure characteristics required for proper running on Discovery 1 and Discovery 2 EFI 3.5L and 3.9L engines. Replacement manifolds restore a consistent mating face where heat and thermal cycling have caused surface distortion or cracking - ensure the left-hand orientation and inlet port pattern match the engine head during installation.

Frequently Asked Questions
ERR7393 collects exhaust flow from the left-side exhaust ports and directs it into the common exhaust stream via a flanged collector that mates to the downpipe. It provides a machined mating face to seal against the cylinder head and helps maintain the correct back-pressure for EFI 3.5L and EFI 3.9L engines fitted to Discovery 1 and Discovery 2. Heat and thermal cycling can cause warping or cracking; replacement restores a consistent flange for correct gasket seating.

If you are unsure of compatibility with your vehicle, you can also confirm by checking against your V.I.N. Simply reach out to us with your V.I.N and desired part number via our Contact page or use our Finding Part Numbers page.
Replace the manifold if there is visible cracking, warping, or an exhaust leak at the manifold flange, or if gasket sealing cannot be achieved. Inspect the manifold during service if there are increased exhaust noises, exhaust smell in the cabin, or changes in engine running.
