SPARK PLUG BRISK AR10IR-OE

BRISK / Ref: AR10C

Performance Features of Brisk Iridium Racing Spark Plug

• Iridium is an extremely durable material that extends the spark plug lifetime by reducing gap erosion. (Iridium/Yttrium series utilize Yttrium enriched ground electrode for increased durability – available in only some shell dimensions).
• Brisk Racing Iridium spark plug "Power Focus" – spark is exactly in the focal point of the reflector, directing the air/fuel mixture during the compression stroke to the center electrode and consequently, after ignition, the propagating flame front toward the center of the combustion chamber.
• Lower required supplied ignition voltage – achieved by utilizing an optimized diameter spark plug center electrode, along with sharp edges of the cut back ground electrode. This feature is beneficial in applications where the stock ignition system is pushed to the limit in modified power applications and the customer does not want to upgrade the ignition system. It is also beneficial for easier cold starts and operation under partially fouled spark plug conditions caused by air/fuel management problems or oil consumption.
• Optimized 1mm diameter Brisk Racing Iridium spark plug center electrode displaces more heat than smaller diameter tips. The cut back ground electrode accumulates less heat, displaces heat more rapidly, and allows for better access of the air/fuel mixture to the spark and easier (less restricted) spread of the flame front immediately after ignition.
  

Key Benefits and Applications

• Iridium is 6x / 8x stronger and has a 1200°C higher melting point than platinum.
• Power Focus - Spark exactly in the focal point of the reflector.
• Lower required supplied ignition voltage.
• Optimized diameter center and cut back ground electrode.
• Less quenching, better air/fuel mixture access = more power.
• Ability to ignite lean mixtures and difficult-to-ignite fuels.
• Suitable for high pressure, high output race engines.
• Good resistance to fouling and easier starts.
