Motorcycle Spark Plug Wires

Style & Spark: Custom Motorcycle Spark Plug Wires

Spark plug wires are a small detail that makes a huge impact. They're a critical part of your ignition system and a key styling element. A set of worn-out or incorrect plug wires can cause poor performance, while a quality set of vintage-style cloth spark plug wires can transform the look of your engine. Whether you're doing a tune-up or a full custom build, we have the right wires for the job.

Choosing The Right Wires For Your Ignition

Not all spark plug wires are created equal. The type you need depends entirely on your motorcycle's ignition system.

• 7mm Copper Core for Vintage Bikes: If your bike has a points or magneto ignition system, you need classic 7mm copper core wire. This is the period-correct choice for vintage bikes, ensuring a strong, unfiltered spark. Our cloth-covered copper core wires provide that authentic, old-school look.
• 8mm Suppressor Core for Modern Bikes: Modern electronic ignitions, radios, or EFI systems are sensitive to Radio Frequency Interference (RFI) produced by copper wires. 8mm suppressor core wire has a carbon fiber core designed to "suppress" this interference, preventing issues with your electronics. If you have an electronic ignition, this is the wire you need.
• Build Your Own with a Custom Kit: For a perfect fit every time, nothing beats building your own. Our universal spark plug wire kits come with high-quality wire and a variety of terminals and boots (straight or 90-degree) so you can create the exact length needed for your custom setup.
• Learn to Do It Right: Making your own wires is easy, and a skill every builder should have. For a complete walkthrough, check out our in-depth guide to making your own custom spark plug wires.
