What is the main benefit of using MPG Plus ignition wires?

The MPG Plus ignition wires are designed to deliver a strong and consistent spark to your engine's cylinders. This improved spark delivery can help your engine run more efficiently and smoothly.

Do these wires come with spark plugs?

No, this product is for the ignition wire set only. It is recommended to inspect your spark plugs when installing new wires and replace them if they are worn or fouled.
