6 Cylinder Engine Overview (Regular V6 Vs Twin Spark Compared)
The gas-powered V6 engine contains six cylinders found in the engine block. It tends to use less fuel than the V8 and is cheaper to manufacture but still provides plenty of performance.
The twin-spark engine may also have six cylinders, but it contains two spark plugs per cylinder. This design improves performance because there is never a lag when waiting for ignition, but the configuration can often be more complicated.
With that said, the twin spark engine does create a cleaner burn and can consume less fuel. Some enthusiasts also think it provides a smoother ride. Still, replacing double the amount of spark plugs can dramatically increase your tune-up cost, so the benefits and disadvantages must be weighed.
How do you know what type of engine you have and how many spark plugs are in a V6? To answer this, you want to reference your vehicle owner’s manual. It will provide you with the engine specifications so you can get the right amount of spark plugs.
