How do you splice spark plug wires together?

Can you solder spark plug wires?

Solder is fine for small connections. The center lead of a plug wire is normally folded back over the outside of the insulation and contacting the crimped terminal 1/2 inch or more. Thats plenty of connection.

Why do spark plug wires go bad?

Vibration damage – Constant wear and tear caused by engine vibration can loosen the electrical connection at the spark plug. This causes an increase in the voltage required to fire the spark plug, which could damage the ignition coil as well as the spark plug wires.

Are spark plug wires universal?

Spark plug wires are commonly direct-fit to work on a specific application. This makes installation very easy; however, you can also find universal spark plug wires that can be cut to fit.

What is inside a spark plug wire?

Description. Spark plug wires have an outer insulation several times thicker than the conductor, made of a very flexible and heat-resistant material such as silicone or EPDM rubber. The thick insulation prevents arcing from the cable to an earthed engine component. A rubber “boot” covers each terminal.

Do spark plug wires need to be separated?

Question: “Do spark plug wires need to be separated?” YES! The high voltage running through a spark plug wire will generate an electrical field around that wire. … If the wires were improperly routed and not separated a problem called, appropriately, Cross Fire would occur.

Can you fix a spark plug?

Changing spark plugs takes about an hour (for a four-cylinder engine) and will save you at least a hundred bucks in labor if you do it yourself. In most cases it’s a simple job that will help to maintain peak performance and the highest possible gas mileage.

Can spark plug wires be too long?

The resistance of a longer wire isn’t really an issue. Unless you were mounting the coil at the other end of the vehicle. Ideally you want to keep them as short as possible.
