Brisk Iridium Performance Spark Plugs

Brisk Iridium Performance Spark Plugs are 6x harder and 8x stronger than platinum, making these spark plugs extremely durable and extending the spark plug lifetime by reducing spark plug gap erosion. This spark plug design is beneficial in applications where the stock ignition system is pushed to the limit in modified power applications, helping to eliminate the need to upgrade the ignition coil. The spark plug ground electrode is cut-back to the center of the center electrode, maximizing spark exposure. This helps with cold starts and does not hinder the flame front propagation into the combustion chamber. An ideal choice for a long lasting OEM performance upgrade.
