Optimize Combustion with Precision Indexing

Achieving maximum power output requires every detail to be perfect, including the orientation of your spark plugs. The Jones Racing Products Spark Plug Indexer is a professional-grade tool designed to help you index your 14mm flat or tapered seat spark plugs for optimal combustion chamber exposure. Properly indexed plugs ensure that the ground electrode does not shroud the flame kernel, leading to more efficient ignition.

Technical Features

  • Design: 9-Hole Indexing Plate
  • Compatibility: 14mm Flat and Tapered Seat Plugs
  • Material: High-Quality Aluminum
  • Finish: Black Anodized
  • Includes: Rotatable Insert

This indexer features a rotatable insert that allows for precise adjustments, making it easier than ever to align your spark plugs exactly where you need them. The 9-hole configuration provides multiple reference points, ensuring you can find the perfect angle for your specific cylinder head setup. The black anodized finish not only looks great but also provides a durable, corrosion-resistant surface that will stand up to years of use in the garage.

Whether you are building a high-compression naturally aspirated engine or a forced-induction powerhouse, spark plug indexing is a proven method to improve throttle response and overall performance. Don't leave power on the table—ensure your ignition system is firing at its peak potential. Trust the professional tools from Jones Racing Products.
