Brisk Iridium Racing Spark Plug

 

PERFORMANCE FEATURES OF BRISK IRIDIUM RACING SPARK PLUG:

Iridium is extremely durable material that extends the spark plug lifetime by reducing spark plug gap erosion.  (Iridium/Yttrium series utilize Yttrium enriched spark plug ground electrode for increased durability – available in only some shell dimensions)

Spark Plug Power Focus – spark plug spark is exactly in the focal point of the "tapered shell reflector" that helps direct air fuel mixture during the compression stroke to the center electrode and consequently, after spark ignition, the propagating flame front toward the center of the combustion chamber.

Spark Plug Lower Required Supplied Ignition Voltage – is achieved by utilization of optimized diameter of the spark plug center electrode, along with sharp edges of the cut back ground electrode.  This spark plug design is beneficial in applications where the stock ignition system is pushed to the limit in modified power applications and customer does not want to upgrade ignition system.  Spark Plug Lower Required Supplied Ignition Voltage is also beneficial for easier cold starts and operation under partially fouled spark plug condition caused by A/F management problems or oil consumption. 

Spark Plug Optimized Center Electrode -   Utilizing a 1mm diameter spark plug iridium center electrode, our center electrode is capable to displace more heat than smaller diameter tips used by other Iridium spark plug manufacturers.  Brisk Iridium Racing Spark Plug cut-back ground electrode accumulates less heat, displaces heat more rapidly, and allows better access of A/F mixture to the spark and easier (less restricted) spread of the flame front.
