Every time you twist the throttle, your engine relies on a strong, consistent spark. Whether you ride a classic Indian Chief, a powerful Victory Cross Country, or a modern Indian Challenger, maintaining a high-quality ignition system is crucial for peak performance, better fuel economy, and reliable starts.
At Witchdoctors, we specialize in V-Twin parts, offering a comprehensive selection of the best Victory and Indian spark plugs and spark plug wires. From dependable OEM-spec replacements to high-performance Iridium upgrades and custom-fit spark plug wires, we have the ignition components you need to unlock the full potential of your American V-Twin.
A spark plug is a small part with a massive job. Choosing the right material directly impacts how your engine runs, especially under the high heat and compression of a V-Twin engine. We stock plugs from top brands like NGK, Champion, and Drag Specialties.
Understanding the material of the electrode helps you choose the right plug for your riding style and budget:
The best spark plug in the world can’t perform if the wire delivering the voltage is weak. We offer high-dielectric, low-resistance spark plug wires designed to ensure maximum voltage reaches your plugs for a powerful, consistent spark.
A: For standard copper plugs, the manufacturer-recommended interval is often between 8,000 to 10,000 miles. For premium Iridium spark plugs, the lifespan is significantly longer, often extending to 15,000 miles or more. Always check your specific motorcycle's owner or service manual for the exact recommended maintenance schedule.
A: Spark plug wires often have a longer lifespan than copper plugs, but they should be inspected for cracks, brittleness, or abrasion at every plug change. Upgrading to a high-performance 10mm or 8.5mm wire set (like those from Trik Wires or MSD) can ensure maximum voltage and better heat resistance, which is especially beneficial for modified or performance-tuned V-Twins.
A: We carry trusted, OE-quality brands like NGK, Champion, and Drag Specialties. For a direct replacement, stick to the part number specified in your manual. For an optimal upgrade in performance and longevity, an NGK Iridium plug is a top choice for the Indian Thunderstroke and Victory Freedom engines.
A: While pre-gapped plugs are common, it is always best practice to double-check the gap using a feeler gauge to ensure it matches your motorcycle’s specification (e.g., 0.034 inches for many Indian models). This ensures the most efficient spark and optimal combustion.
A: Common signs of failing wires include engine misfires, a rough or erratic idle, backfiring, loss of acceleration power, or noticeable cracking/brittleness on the wire insulation. Replacing old or worn spark plug wires is an easy and cost-effective way to restore peak performance.
