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

The MPG Plus wires use a special spiral core that has lower electrical resistance. This allows a stronger spark to reach the spark plugs, which can lead to more efficient combustion and potentially better fuel economy.

What materials are these ignition wires made from?

These wires feature a 7mm silicone jacket, which is known for its durability and resistance to heat and abrasion. The internal construction uses a high-performance spiral core.

Do these wires come with everything needed for installation?

This set includes the ignition wires themselves. It's always a good idea to check if your vehicle requires any additional hardware or specific tools for spark plug wire replacement.

About this part

Product Details

These Granatelli MPG Plus ignition wires are built with a unique 7mm silicone jacket and a high-performance spiral core. This combination helps deliver a strong, consistent spark to your spark plugs, which is key for efficient combustion in your 8-cylinder, 6.6L Mercury engine. Having a solid spark means your engine can run smoother and potentially get more out of every drop of fuel.

The spiral core inside these wires has a lower resistance than standard copper wire, allowing more energy to reach the spark plug. This updated design can lead to improved throttle response and a more reliable ignition system overall. They are designed to fit right into your existing setup, making the replacement process straightforward.
