Do new ignition wires make difference?

There isn’t any performance to be gained from spark plug wires, just better build quality, which gives you not a better spark, but rather maintains an appropriate spark for more miles/years before their performance degrades to the point of needing replacement.

Does it matter what spark plug wires you use?

Does size matter? For overall spark transfer, not necessarily. However, thicker wires, like these Moroso Super Max II 11mm wires, can provide added RFI suppression and insulation. That’s why it’s important to select a good quality set of spark plug ignition wires to deliver juice to your spark plugs.

What’s better 7mm or 8mm spark plug wires?

8mm spark plug wires are a heavier gage wire than the 7mm type. A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs. Additionally, the 8mm wires have a thicker outer coating that keeps the core safe from damage.

Can spark plug wires increase horsepower?

How long do ignition leads last?

The ignition cables on a car are made to last about 60,000 miles before they have to be replaced. In some cases, the wires will need to be replaced due to the rubber boots on the end getting damaged and now allowing for a good connection with the spark plugs.

What size spark plug wires should I use?

Most manufacturers recommend an 8 or 8.5mm plug wire on most applications. Exceptions would be an all-out race car or a street rod where EMI/RFI suppression is not a concern, but weight and appearance are. In which case, a 5 or 7mm wire might be a better option.
