It is manufactured to the original Volvo Penta dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. Inlet guide; nominal outside diameter 16 mm, bore 9.53 mm and length 82 mm where specified. In service, it guides the inlet-valve stem accurately and transfers heat from the valve into the cylinder head. Selection must be confirmed by OEM part number 20355012, the exact engine or product model, serial number and installed configuration.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  TWD, TID, TD, TAMD, TAD\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\n Full model list at the end of this description.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Genuine Volvo Penta OEM valve guide\n \u003c\/li\u003e\n \u003cli\u003e\n  OEM part number 20355012\n \u003c\/li\u003e\n \u003cli\u003e\n  Inlet guide; nominal outside diameter 16 mm, bore 9.53 mm and length 82 mm where specified.\n \u003c\/li\u003e\n \u003cli\u003e\n  Measure the cylinder-head bore and valve stem, install with the specified interference and finish the guide bore to Volvo Penta service limits.\n \u003c\/li\u003e\n \u003cli\u003e\n  12 used per assembly\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Guides the inlet-valve stem accurately and transfers heat from the valve into the cylinder head.
