How many valves does the 2007 Chevrolet Impala have?

The 2007 Chevrolet Impala had either 4 valves per cylinder (in the V6 engine) or 2 valves per cylinder (in the V8 engine, if so equipped). Therefore, the number of valves depends on the engine.

* V6: 4 valves/cylinder * 6 cylinders = 24 valves

* V8: 2 valves/cylinder * 8 cylinders = 16 valves
