181016OEM Center Exhaust Manifold for Cummins ISM / L10 / M11 Engines application

It’s designed as a center exhaust manifold for Cummins ISM applications and is commonly referenced for Cummins L10 exhaust manifold and Cummins M11 exhaust manifold fitments as well. Always confirm compatibility by matching the MPN (181016OEM) and your engine’s exact configuration before ordering. If your setup uses a different mount style or position, a different manifold may be required.

Match the MPN and product description to your existing part and verify placement as a Cummins ISM center exhaust manifold (center position). Comparing casting numbers, port layout, and hardware locations is a reliable way to avoid fitment issues. If you’re cross-shopping, note that similar PAI 181016OEM manifold listings may have related “low mount” or kit options that are not interchangeable.

Yes—replacing gaskets and any worn fasteners is strongly recommended when installing a diesel engine exhaust manifold to reduce the risk of leaks and repeat labor. Inspect mating surfaces for flatness and clean them thoroughly before assembly. After installation, recheck for exhaust leaks and follow proper torque procedures for your Cummins application.
