You can purchase bulk wire and the applicable terminals and boots to create your spark plug wires from scratch, or you can buy the universal semi-terminated kits offered by many manufacturers that come terminated at the spark plug end and all you have to do is cut the wire to length at the distributor cap end and install the appropriate terminal. Here we want to put the right angle boot over the wire (either end). It is this very reason we highly recommend building your own custom spark plug wires. Next, seperate your spark plug wires from your coil wire. This is especially true if you are deviating from the factory plug wire routing (going around the valve cover now instead of over it for example). CDI 631-0023 Spark Plug Wires The CDI 631-0023 is a 5 pack of Spark Plug Wires designed for Mercruiser, OMC, and Marine Power engines. Sure, they'll fit, but they may not have just the wire length you're looking for to produce a clean installation. While many people will decide to simply buy pre-terminated plug wire kits that say they fit a specific year range of Ford or GM engines, the truth of the matter is, these wire kits are semi-universal.

Replacing your spark plugs and/or wires is money well spent to have your vehicle running smoothly, dependably and efficiently.You've put a lot of time, money, and effort into building a powerful engine for your project and now that it's down on the mounts and you're getting everything wired up it is time to consider your ignition system and running new plug wires. Badly misfiring plugs can cause expensive damage to a vehicle's catalytic converter, so it's best to take care of them before that happens. can also clean the wires up, snip them, and rethread them to reconnect the spark plug wires. Ask your service advisor to let you know when yours should be changed. Other sputtering issues can be caused by an ignition issue. Spark plugs are made out of different materials and some last far longer than others. Your vehicle's manufacturer recommends changing wires and/or plugs at certain intervals. A closely related problem is failing spark plug wires, and a technician will test for both possibilities… and more. Many have more than one of these things, and a few have all three.

If you're not getting spark to one or more cylinders, this could point to a problem with a spark plug wire. Over time, spark plug wires and boots may be damaged by heat or wear with age. They feature a boot at each end and an insulated conductive core to carry the current. But the problem could be your spark plugs.

They typically consist of a conductive core surrounded by several insulating layers, as they are designed to carry very high voltages. When's the last time you thought about spark plugs? You probably don't remember. Spark plug wires are a component found in many internal combustion engines.
