What to consider before buying

When choosing ignition coil leads, ensure compatibility with your vehicle's engine and ignition system. Check wire length, connector type, and resistance rating. High-performance wires with lower resistance can improve spark, but may cause radio interference if not shielded. For daily drivers, OEM or quality aftermarket sets like NGK or Denso offer reliable performance. Budget options work for older cars but may need replacement sooner.
