Intake Exhaust Valves Fit 03-14 Infiniti G35 FX35 I35 M35 Nissan VQ35DE VQ40DE. The main function of an engine valve is to open and close rapidly. This allows the air and fuel charge to enter the combustion chamber and after ignition, the exhaust valve allows the waste gases to flow out into the exhaust system. Each cylinder has at least one intake and one exhaust valve. Good engine performance depends on valve condition. Worn guides or stems and burned or badly seated valves allow gas to escape under compression, resulting in poor starting and loss of power. Symptoms of a bad or failing engine valve: engine misfire, excessive oil consumption. Be sure to have your engine valves replace with aftermarket replacement engine valves as soon as it starts to give you trouble.
