Land Rover Part Number: LR002447 - Inlet Valve - Cylinder Head - AJ-V8
LR002447 is an inlet valve for AJ-V8 cylinder heads. It controls intake airflow into the combustion chamber on the 4.2 litre supercharged and 4.4 litre AJ-V8 engines, opening and closing as part of the engine's breathing cycle. Located in the cylinder head, the valve works with the valve seat and valve spring to form a gas-tight closure when closed and provide a clear passage when open. Replacement valves must match the cylinder head specification for these AJ-V8 engines to maintain correct seating and combustion efficiency.
