Sierra 18-8527 Stainless Exhaust Manifold Mounting Kit for Chrysler 318-360 CID Engines (1966 & Up)

The Sierra 18-8527 is a stainless steel exhaust manifold mounting kit built for Chrysler 318-360 CID marine engines (1966 and up). It supplies the mounting hardware needed to secure the exhaust manifold to the engine block, using stainless steel construction for added corrosion resistance in the wet, salt-exposed environment around a marine exhaust system. This kit is designed to pair with Sierra's 18-1940 exhaust manifold, giving installers the hardware set required for a complete manifold mounting job without having to source individual bolts separately.

Because the manifold, end caps, risers, and elbows in this exhaust system are matched components, using the correct mounting kit helps ensure a proper seal and secure fit at the manifold's mounting points. The stainless steel finish of the 18-8527 distinguishes it from Sierra's standard 18-8526 kit, offering better long-term resistance to rust and corrosion for boat owners who want extra durability in their exhaust hardware.
