Built to meet or exceed the quality of the original equipment part it replaces, this valve is manufactured for reliable performance in the demanding conditions of marine engine operation. Each valve is a single-piece steel component sized precisely at 2.02 inches to match factory intake valve specifications for applicable GM V-6 and V-8 engines.\u003c\/p\u003e\u003cp\u003eIntake valves control the flow of the air-fuel mixture into the combustion chamber and must withstand repeated high-temperature cycling without deforming or failing. The 18-4735 is designed as a like-for-like replacement so it installs using the same valve train components, seats, and guides as the original valve, without requiring modification. It ships as a single valve, allowing engine builders and service shops to order exactly the quantity needed for a full valve job or a single-cylinder repair.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-4735\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Intake Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Size:\u003c\/strong\u003e 2.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e GM V-6 \u0026amp; V-8 engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.27 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eGM V-6 \u0026amp; V-8 engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-4735 intake valve fit?\u003c\/strong\u003e The Sierra 18-4735 is built for GM V-6 \u0026amp; V-8 engines used in marine applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is this intake valve?\u003c\/strong\u003e It measures 2.02 inches, which is the intake valve head diameter for the Sierra 18-4735.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-4735 an intake valve or an exhaust valve?\u003c\/strong\u003e This is an intake valve.
