Service & Installation Notes
General service guidance only. Use the service manual for your exact engine and exhaust configuration.
- Ensure the engine is shut off, completely cool, and secured against accidental starting before beginning work on the exhaust system.
- Support heavy exhaust elbow or riser components during removal and installation to prevent strain on the manifold mounting surfaces.
- Clean and inspect the mating surfaces at the exhaust manifold-to-elbow/riser joint, removing old gasket material while protecting the sealing faces from scoring.
- Compare the new gaskets directly with the joint layout and port orientation before reassembly, and follow the engine manufacturer's service manual for fastener tightening procedures.
- Inspect the joint after initial operation; if any exhaust or sealing abnormality is observed, shut the engine down and recheck the installation.

Questions Before Replacement
Does this listing include the exhaust elbow or riser casting?
No. This product is a two-piece exhaust elbow/riser gasket set for sealing the joint between the exhaust manifold and the elbow/riser. Castings and mounting hardware are not included.
How should I distinguish between similar reference numbers like 18-0943-1, 18-0943-2, 913783, and 913784?
Match the full part number including any leading zeros and suffixes. Do not assume 18-0943-1 and 18-0943-2 are interchangeable, and pay close attention to the final digit when comparing 913783 and 913784 against your engine parts list.
