Spark Plug Wires

Spark plug wires are a vital component of any engine ignition system, delivering the electrical current from the distributor or coil to the spark plugs. High-quality spark plug wires can improve engine performance by ensuring a more efficient transfer of electrical energy, resulting in a stronger and more reliable spark. At JEGS, we offer a wide selection of custom and universal spark plug wires designed to fit a variety of applications and engine types, including racing and performance vehicles. Our spark plug wires are made from high-quality materials to ensure long-lasting performance and come in a range of colors and styles to match your personal style. Whether you're upgrading your ignition system or just looking for a replacement set of spark plug wires, JEGS has you covered.

Yes, the thickness of your spark plug cable can make a difference. Thicker spark plug wires can provide a lower resistance path for the electrical current to flow through, which can result in a stronger spark to ignite the fuel mixture in the engine. Thinner wires may have higher resistance, which can reduce the strength of the spark. The thickness of the wire can also impact the durability and lifespan of the wire. However, it's important to note that the appropriate thickness of the spark plug wire can vary depending on the specific vehicle and its needs. It's important to consult with an expert or refer to your vehicle's manual for the appropriate spark plug wire thickness. For American V8 engines, 8mm spark plug wires are the most common size for most applications.

Spark plug wires are a crucial component of any engine's ignition system. Over time, the heat and vibration from the engine can cause the wires to wear out, leading to misfires, reduced power, and even engine damage. It is important to replace spark plug wires at the first sign of wear or damage, which can include cracks or breaks in the insulation, corrosion or rust on the terminals, or a decrease in engine performance. Additionally, spark plug wires should be replaced as part of regular maintenance intervals, typically every 80,000 to 100,000 miles, to ensure that your engine is running at peak performance.

The cost of replacing spark plug wires can vary depending on the type of vehicle and the brand of spark plug wires. Basic spark plug wires can cost as little as $20, while high-performance wires can cost upwards of $100 or more. Some brands also offer kits that include spark plug wires, spark plugs, and other necessary components for a complete tune-up, which can increase the cost. It's important to consider the quality of the spark plug wires and their compatibility with your vehicle's ignition system when deciding on a purchase. However, investing in high-quality spark plug wires can improve engine performance and fuel efficiency, making it a worthwhile investment in the long run.
