The number one job of any spark plug wire is to transfer an electrical charge from your ignition to your spark plugs. The challenge is to get the maximum amount of this charge to the plugs without creating interference (EMI or RFI) for nearby electrical components.
How do you protect spark plugs from high voltages?
To do this successfully, they need to be covered in thick insulation to prevent high voltages jumping off the wire before it reaches the spark plug and a rubber boot at each end. The boot protects the metal connectors from moisture, corrosion, oil and other contaminants.
How do you wire a spark plug to a distributor?
Crimp the terminal onto the wire and slide it into the spark plug boot. General best practice is to leave a 1/2in or so of slack in the wire length to prevent it from tugging on the distributor. “Anything you do to make power is going to develop heat, and that’s going to affect the temperatures under the hood,” Fordyce points out.
How do I know if my spark plug wires are good?
Attach the test light to a good engine ground. With the engine running, move the test light along the length of each spark plug wire. If a spark jumps from a plug wire to the test light at any point, this is an indication that the insulation has broken down, and the spark plug wire should be replaced.

What is the resistance of spark plug wires?
Resistance: Rated in ohms-per-foot, resistance is the ignition wire’s tendency to resist the flow of the electric current.
What is EMI wire?
This is referred to as EMI or RFI and can wreak havoc, especially in sensitive radio communications. Some wires are made to produce minimal resistance. Others are designed to suppress EMI. Spark plug wire manufacturers use different core materials and designs to strike the right balance to achieve their desired goal.
What is the purpose of the Conductive/Suppression layer on spark plug wire?
Conductive/suppression layer: Some manufactures add another layer below the insulation as an added safeguard against energy loss or EMI/RFI. Finally, there’s the core. The core largely dictates the performance of the spark plug wire.
What type of core is used for spark plugs?
Again, some cores offer low resistance while others provide better EMI/RFI suppression. The most common types of spark plug wire cores are as follows: Carbon Core: This is the common OEM-style core used on most modern vehicles. It offers excellent RFI suppression but also creates more resistance than other styles.
How many ohms does MSD 8.5mm Super Conductor have?
MSD 8.5mm Super Conductor wire sets use a special helically wound core that has just 50 ohms of resistance-per-foot but offers RFI suppression equal to a 1,500 ohm wire. That's the advantage of a spiral core.
What is a solid core spark plug?
Solid Core: Solid core spark plug wires typically utilize stainless steel or copper, which conducts electrical current very well. For that reason, solid core wires have lower resistance than other wires to get maximum energy to the plugs.
What is a bad spark plug wire?
Bad spark plug wires share similar signs and symptoms with many faulty engine components like spark plugs, ignition coils, fuel filters, to mention just a few. When you notice the symptoms above, the good idea is to test your spark plug wires to ensure they are the cause.
Why does my spark plug not spark?
It is caused as a result of incomplete or erratic combustion. As spark plugs are designed to create Sparks at predetermined intervals, Faulty spark plug wires will not transmit the required spark from the distributor, or ignition could resulting in an engine misfire.
Why do spark plugs lose power?
Reduced engine power: The engine spark plugs need undeteriorated electrical conduction to ensure a predetermined spark during the combustion process. Any deterioration on the spark plugs or spark plug wires will negatively affect the combustion process, leading to loss of engine power.
How to install a new ignition cable?
To properly install ignition cables, push one side of the new ignition cable boot on the ignition coil or distributor first and fix the other end on the spark plug. Make sure the cables sit well to avoid wires dislodging from the cap. 3. Hold the spark plug wire firm on the boot and gently twist and push in the cable.
What happens when spark plugs fail?
When they start failing, you will notice several symptoms of faulty ignition leads that pop up to tell you something is wrong. Failure to track down the cause of these signs and fix them on time might lead to more significant problems. Let’s quickly look at the common symptoms of lousy ignition cables.
Why is my car's spark plug not working?
It could be due to a corroded battery terminal, lousy starter, lousy injectors, or faulty ignition leads. Aside from the causes mentioned above, there are some other factors as well. However, defective spark plug wires can be the culprit without prior notice.
How to check for electrical leaks in a car?
Turn on the engine and check for electrical leaks: Turn on the engine and carefully examine the wires. Snapping noise around the wires and the distributor or ignition coil indicates electrical leaks. Do not touch the wires while the engine is idling to avoid electrical jolts. Step 3.
Do you check wires before you put them on an engine?
And once all the wires are built, it’s important to check your work before they go on the engine. “I typically remove all of them, clean any grease or other debris off of them, and then check the resistance of each of them to make sure there aren’t any issues.
Does dielectric grease help with spark plugs?
“It’s designed to help seal the boots to the spark plug or distributor cap, which helps to prevent corrosion and, to some extent, helps to keep the spark from jumping to ground.
Do you check the resistance of spark plug wires?
When you’re doing a tune-up, you should always check the resistance of the wires and make sure the wire is not degrading.”. And that means that even if a spark plug wire looks fine on the outside, it’s not a guarantee that it’s internally sound. “If it degrades, it’ll normally create more resistance,” Fordyce says.
Do you need spark plug wires for LS?
Coil- near-plug engines, such as the ever-popular LS, still require quality spark plug wires. Often, coil relocation or non-factory valve covers require custom wires. MSD offers the correct boots and terminals to build wires for these setups as well.
Why do spark plugs need to be in good condition?
For proper engine combustion and maximum engine power, the spark plug wire must be in good condition to ensure electrical current is passed into the engine. #8 – Engine surging: When you notice an engine surging issue in your car, act fast. This is a common sign of a bad spark plug wire in a car.
How do spark plugs work?
Spark plugs ignites the combustion chambers to burn the mixture of fuel and air to enable the vehicle to move. When the spark plug is bad, the engine will not function well. Usually, car spark plugs last long. However, the longevity depends on the type of spark plug.
What does it mean when a spark plug is bad?
Engine misfiring is one of the known symptoms of a bad spark plug wire in a car. This usually occurs when there is incomplete engine combustion. Engine misfires, because the cylinders are not working or firing fine. With a bad spark plug, the vehicle will halt and continue.
What happens if you don't have spark plugs?
