There are two main goals for high-performance spark plug wires: suppressing voltage interference and transmitting the spark’s energy to your plugs. If the resistance is too high, the energy to the spark plug decreases, generating poor performance. Too low, and it interferes with things like car audio, GPS, fuel injection, or generating crossfires. Discover the best high-performance spark plug wires on the market today.

 

Crossfire occurs when the plug wire becomes compromised or the wire resistance is too low. This allows the spark energy to go to an adjacent plug wire, causing it to fire from the wrong plug at the wrong interval.

 

High-Performance Spark Plug Wires Buying Guide

 

The best wires use a spiral wound core. It should be well insulated to protect against radio frequency interference (RFI). The spark plug wires should also contain a solid fit at the spark plug and distributor cap. 

To get the best performance from your ignition system, secure the wires using a spark plug wire loom kit and ensure they are properly routed. It is advisable to conduct regular inspections of the secondary ignition system as well as to look for traces of abrasion, crossfire, wear, and heat damage. The components work together to provide the best spark to light the air/fuel mixture in the combustion chamber.

 

It is best to invest in a Heli-Core wire as it will be the best upgrade over the ones that were factory installed. Another popular choice is Street-Fire wires.

 

High-performance spark wires have lower core resistance, which provides a superior degree of radio suppression and better resistance to engine chemicals and heat.

 

Benefits of Good Spark Plug Wires

 

There are many benefits to replacing your spark plug wires regularly. Doing so:

 

• Improves Mileage: Bad spark plugs/spark plug wires may use more fuel. High-quality wires allow the spark plugs to start quicker and the engine to run more efficiently.

 

• Increases Engine Performance: It will instantly provide a spark to the spark plug. Standard OEM wires may start the vehicle, but they weaken over time and do not start the engine properly. This can cause misfires, lack of power, and lower idle.

 

• Saves You Money: Routinely changing spark plug wires can save you money. Driving your vehicle with bad wires can damage the car. They may end up harming the spark plugs, resulting in higher repair costs.

 

• Reduces Radio Frequency Interference: Carbon spark plug wires have an increased resistance against electronic frequencies and reduce the amount of RFI created by normal ignition system operations. RFI impacts radio reception and interferes with computer systems/sensors in the car.

 

Spark Plug Wire Types

• Fixed Resistor Wires: These plug wires are generally for European cars. They have copper and steel wires with resistors in spark plug boots.

 

• Magnetic Resistance Wires: Also known as inductance wires, these are found in Japanese vehicles like Hondas, Toyotas, and Acuras. They have spiral cores with copper or nickel alloy wires, making them less resistant to electrical flows. This means that they need less current for a spark.

 

• Distributed Resistance Wires: These are impregnated fiberglass carbon core wires and are very common in wire sets in most vehicles. The carbon is what gives your wires higher resilience to RFI noise.
