Spark Plugs

Spark plugs ignite the air-fuel mixture in your engine's cylinders, making them one of the most critical components for reliable starting, smooth idling, and optimal fuel efficiency. Whether you're performing routine maintenance, chasing an elusive misfire, or building a high-compression forced-induction engine, the right plug makes a measurable difference.

This collection brings together spark plugs for a wide range of applications, from daily-driven commuters to dedicated race cars. Use the filters to narrow by thread size, reach, and heat range, or browse by electrode material:

  • Copper – Excellent conductivity, ideal for older engines and performance applications where frequent changes are acceptable.
  • Platinum – Long service life and consistent performance, commonly specified for modern engines with high-energy ignition systems.
  • Iridium – Extremely hard, fine-wire center electrode reduces voltage requirements and extends change intervals, often found in late-model and high-output engines.
  • Double Platinum / Double Iridium – Enhanced durability for waste-spark ignition systems, with precious metal on both electrodes.

When selecting a plug, verify the manufacturer's recommended heat range and gap setting. A plug that's too cold may foul during low-speed driving, while one that's too hot can lead to pre-ignition and engine damage. All plugs in this collection meet or exceed OEM specifications for durability and performance, giving you confidence with every ignition cycle.
