Types of Spark Plug Wire Sets

All spark plugs are designed to achieve the same effect. However, their construction and how they achieve the role and purpose that they have been designed for is what varies hence the various types. Below are the types you expect to come across on the market.

#1. Distributed Resistance Spark Plugs

Many of the American vehicles are designed to use and work with distributed spark plug wires. They are constructed with very fine strands of fiber glass that have been bonded with carbon. The carbon gives these spark plug wires that higher resistance. The high resistance is great and actually beneficial.

The high resistance helps to reduce the Radio frequency interference noise that is generated by the normal ignition system operation. Agreed the RFI does not only ruin radio reception but also, in some severe cases RFI interferes with the sensors and computers that have been designed to control the working of the engine.

If your car came with this type of spark plug wires, work hard, devoid of the price buy replacements of the same type.

#2. Inductance Style Plug

Japanese cars like Acura, Toyota, Lexus and Honda come equipped with MAG (inductance) spark plug wires. These are designed from spiral cores wounded with a nickel alloy or copper wires. The winding spiral wire creates a magnetic which results in the reduction of RFI. The fact that MAG wires feature lesser electrical resistance means that they need lesser current to fire up the spark plug and therefore start the engine.

#3. Fixed Resistor Spark Plug wires

European car manufacturers prefer these types of spark plug wires. They are manufactured from copper or steel wires and feature resistors inside their spark plug boots.

Criteria to Choosing Spark Plug Wire Sets

Knowing the types of spark plug wires that there are, is very different from choosing the best for your car. You need to know what will make a specific type of plug best for your car while considering some factors; those that you will have to compromise on and those that you will enjoy regardless.

If you are a daily driver then the OEM-style spark plug wires will work just fine for you. However, you should note that the carbon cores wear out pretty fast and will as such require replacement all too often if you do not want them to misfire or affect your ca’s acceleration. Quality carbon spark plugs however provide great service and far less noise and interference.

If you have a race car with an old school ignition set up or a carburetor, you will need to get spark plug wires that have lower resistance. Solid core wires will benefit your car. In such cars, the noise from the engine ignition system is not a factor since you have no use for the radio and the noise is masked with the engine roars.

If you have high performance applications, the kind that feature the latest ignition systems and are easily affected by the RFI, then Spiral core wires are best. These types of spark plug wires feature low resistance delivering maximum voltage to the plugs making them perfect for cars that need to consume a lot of fuel. You should note however that these are the most expensive on the market; and especially if you are looking for the largest diameter wires.

When to Change Spark Plug Wire

To know when spark plug wires need changing, you will need to conduct tests with an ohmmeter. An ohmmeter is a device designed to measure the amount of resistance in a wire. Now we have already established that there are different types of spark plug wires with distributes resistance spark wire plugs having a resistance value of between 3000 and 12000 Ohms per foot.

Fixed resistor and MAG spark plug wires have much lower resistance. But the point here is not the amount of resistance but rather the consistency of the readings between the wires at hand. Measure the length of the wires and the resistance of each park plug wire and have it written down.

After you have all the values, make the comparison. Spark plugs with insanely higher resistance than other plug wires of the same length are bad. This should signal time for change.

How to Change Spark Plug Wire

The best advice you can get on how to change your spark plug wires is to remove the old spark plugs wires one by one. Each spark plug wire you remove needs to be replaced with a new wire of similar length and before any other wire is removed. Have the new wire follow the same route as the old route snapping it onto the exact same clips on the wire looms.

Misrouting the wire could create a misfire which will engage your engine light and give you a massive headache trying to fix it. After placing the wire on the right place, it is time to apply tune up grease on the spark plug boots of the new wires to help prevent voltage leakage. The grease will make future removal a breeze.

Last but not least, replace the loom clips that have broken in the process. You should never leave plug wires dangling as they may touch metal parts on the engine and wear away faster than normal eventually causing misfires.

Tools to Change Spark Plug Wire

Below are the tools you will need to make the spark plug wire changes a breeze.

#1. Spark Plug socket with Swivel Locking Mechanism

A GearWrench spark plug socket that features an inbuilt spark plug socket extension will provide you with the maximum turning angle with lots of clearance to work tight space. The socket and the locking extension are locked together permanently and as such you need not worry about the two disconnecting as you remove the plug.

#2. Spark plug boot puller pliers

Pulling the wires directly can damage the wires by separating the wire from the boot. To break loose the plugs, use the boot puller pliers. Simply grab and pull.

#3. Spark plugs wobble sockets

These sockets are designed to fit into tight spaces. They are smaller than ordinary spark plugs and are easy to use. This alone makes a huge difference between removing old spark plugs and having a frustrating time under the hood.

#4. Boot grease

Spraying the spark plug boot grease into the boot will help prevent voltage leaks. This also makes the removal in the next change easier.
