On a 1997 BMW 740i, the intake valves are located within the engine's cylinder heads, specifically for each of the eight cylinders in the V8 engine configuration. To access them, you would need to remove the intake manifold and other components that obstruct the cylinder heads. The intake valves are responsible for allowing air and fuel mixture into the combustion chambers during the intake stroke of the engine cycle.
