Sierra 18-4735 Intake Valve, 2.02 Inch, Fits GM V-6 & V-8 Engines

The Sierra 18-4735 is a 2.02 inch steel intake valve engineered as a direct replacement for GM V-6 and V-8 marine engines. 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.

Intake 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.
