This Genuine Honda exhaust stud is a high-quality steel fastener designed to secure the exhaust manifold firmly to the cylinder head on Honda GX-series engines. Engineered for reliability in demanding environments, it maintains a tight, stable seal to help prevent exhaust leaks that can cause loss of power, excess noise, and reduced engine efficiency.
