A Quick Overview of Spark Plug Wire
Since spark plugs require an extremely high voltage to “ignite,” spark plug wires deliver high voltage current from the ignition coils to the spark plugs.
A center conductor, one or more layers of insulation, an exterior sheath, a spark plug, coil, or magneto terminal, a distributor terminal, and insulating terminal boots are all basic components of spark plug wires.
Spark plug wires are designed to:
- Transmit high voltage pulses without being destroyed.
- Remain electrically isolated from the ground.
- Not be affected by the high temperatures present in engine compartments in order to deal with the high voltages produced by magnets and coils.
Different Types of Spark Plug Wire
When it comes to engine types, there are generally three types of spark plug wires. These are the three categories:
Inductance/Magnetic Resistance Wires: Magnetic resistance spark plug wires, also known as inductance wires, are more common in Japanese cars like Acuras, Toyotas, and Hondas. Spiral cores woven with nickel alloy or copper wires are used to construct them. Because the material is more conductive to electricity, it needs less current to ignite a spark.
Extended Resistance Wires: These wires are the most prevalent of all wire sets used in today’s cars and are made up of fiberglass-impregnated carbon core wires. The carbon in the wires is what makes them more resistant to RFI noise.
Wires of Fixed Resistor: Fixed resistor spark plug wires are more common in European-style automobiles. Steel and copper wire are used, and the spark plug boots incorporate resistors.
Special Wire Requirement for SBC With Headers
Spark plug wires transmit thousands of volts to the spark plugs – up to 45.000V, depending on the application. So, they must be coated in heavy insulation and have a rubber boot at either end to prevent excessive voltages from leaping off the wire before it reaches the spark plug. In addition, the boot keeps moisture, rust, oil, and other impurities out of the metal connections.
Furthermore, wires must be carefully made to meet OEM specifications, ensuring perfect ignition, excellent engine performance, cost-effective fuel usage, and EMI suppression (Electro-Magnetic Interference).

How to Replace a Spark Plug Wire
Spark plug wires must be changed on a regular basis to maintain a vehicle’s engine running smoothly. Here is a step-by-step procedure for you to follow.
Step 1: Taking Out the Old Spark Plug Wires
Star with the longest wire, remove and replace one wire at a time. Make sure you’re only pulling on the boot and not the wire. If you jerk or yank on the wires, the connection may be broken.
Step 2: Sort Out the New Wires
Match the longest wire from the new set to the vehicle’s longest wire, then the next longest, and so on. Because various wire manufacturers produce varying lengths, don’t match for length.
Step 3: Install the New Wires
Push the new spark plug wire boot on one end of the module, then the other end to the spark plug to install a new wire. If the boot does not sit properly, gently roll the edge of the boot to let out extra air.
Step 4: Check the Wire
Don’t pull on the wire. The wire will simply go on, and you will hear a “click” when it is properly positioned. If the wire falls off easily when pulled back tightly, it was put incorrectly.
Step 5: Placement for the New Spark Plug wires
To prevent cross-firing, it’s important to route spark plug wires to cylinders in the same order as the firing order. Also, keep the new spark plug wires away from metal items like exhaust manifolds.
Things to Consider Before Replacing Spark Plug Wire
- Before you start, make sure your car’s engine is cool.
- When the engine is cold to the touch, remove the spark plug wires.
- Wipe the spark plug insulator, and distributor cap towers clean before inserting new wires.
- Connect the plug wires in the same way they were before.
- Avoid routing wires from sequentially firing cylinders adjacent to each other to avoid arcing.
- Like antennae, metallic wire sets can emit ignition noise.
- Always listen to the radio with the hood closed and locked.
- Ensure that the spark plug wires are not connected to a sensor wire.
Importance of Spark Plug Wire
The ignition system of an engine relies heavily on spark plug wires, commonly known as ignition cables. Spark plug wires connect the coil to the spark plug in automobile engines with a distributor or remote coil pack.
In the combustion chamber of your engine, however, the ensuing spark ignites the air-fuel combination. The ignition coil, which converts low-voltage electricity into extremely high voltage, is the first step in this process.
The wires are responsible for igniting each spark plug, and they require just as much attention as the plug itself. Choosing the best spark plug wires for chevy 350 with headers is important as a result.
FAQ
Use tape with plastic covers or any form of spacer below the wires to protect them. This will provide some spacing between the headers and protect them from melting. You can also employ insulating boots or sleeves to effectively avoid melting.
Another option to try is zip ties. These gadgets keep wires away from hot surfaces. However, you must ensure that the wires are properly secured to prevent them from being worn down or accidentally damaged.
High-performance spark plug wires have a lower core resistance, are more resistant to engine heat and chemicals, and have better radio suppression.
The wires feature thicker exterior materials to resist heat and chemical damage, as well as improved radio frequency suppression.
That’s why high-performance wires will enable your spark plugs to ignite faster and run more efficiently.
Of course, it matters. There are a variety of spark plug wires on the market. Each engine necessitates a unique product with precise dimensions. If your sbc has a header, you’ll need to put sbc under header spark plug wires to keep the wires from melting.
That’s why we like to suggest that you follow the manual and pick your wires according to the instructions mentioned there. It will help you get the right one.
Yes, you should use OEM spark plug wires. However, unless you’re convinced that a high-performance product won’t negatively damage your car, you should stick to OEM-type spark plug wires. Another key consideration is to always buy new spark plug wires since you never know how well-worn secondhand components are.
Final Suggestions
