Description
Overview:
This Exhaust Bolt/Stud 8 x 22 mm is a Genuine Honda part designed to secure exhaust components on Honda petrol engines. Made from robust steel to cope with heat and vibration, it fastens the exhaust manifold or muffler to the cylinder head, helping maintain a gas-tight seal.

It is suitable for a range of Honda GX and GXV series engines, including the GX610U1 and GX620U1. Using the correct genuine stud helps prevent exhaust leaks, reduces the risk of stripped threads, and supports reliable engine performance over time.
