replace spark plug wires

Hello,

The price difference can be due to being factory replacement parts or aftermarket replacement part.
Also, the quality and warranty of the product will also impact the price, as well as the place of manufacturing.

Even though all of them will do the same thing, typically the factory replacement parts (OEM) works better in most cases. Usually, those OEM parts costs more than the aftermarket parts.

So, you can buy the $85.00 or the $140.00 part to complete the job. However, the longevity can vary depending on the quality of the product.

The spark plugs price can vary depending on the material. Platinum tipped plugs will cost more than the copper plugs. Best option would be to follow the guide on the owner's manual as it will recommend the ideal type.
