Description
Overview:
This exhaust manifold is a genuine Honda part for GX-series petrol engines, including the GX240 and GX270, and is also suitable for larger GX340 and GX390 variants. It channels hot exhaust gases from the cylinder head to the silencer, helping maintain correct flow, back pressure, and engine efficiency. Built from robust, heat-resistant metal with precisely formed mounting faces, it provides a reliable, gas‐tight path under high temperatures and vibration. The manifold is designed to match original Honda dimensions and hole patterns for dependable alignment and sealing. It is ideal for routine replacement during servicing or when restoring performance on hardworking equipment. Genuine Honda quality with MPN 18330ZE2W00 (also 18330-ZE2-W00) supports long service life and consistent fit on compatible Honda GX engines.
