Brisk Iridium Racing Spark Plug - 1.8T/2.0T FSI/TSI - 3.0T SC - Hybrid/Big Turbo/Pulley Performance

*Note: This is one heat range colder plug, ideal for hybrid or big turbo applications, as well 3.0T SC with pulleys, for stock turbo/pulley applications please use part number DOR12IR

BRISK Iridium spark plugs have high ability for ignition of air-fuel mixture in combustion chamber. Small diameter of centre electrode tip made from iridium alloy and ground electrode centered through cutting to centre electrode decrease demand on voltage supplied by ignition system. Iridium alloy has high value of melting point with high resistance to erosion. The shape of ground electrode does not impede flame front propagation in combustion chamber. Good access of mixture to electrodes increases functional properties of spark plugs, power and vehicle’s acceleration.

KEY BENEFITS AND APPLICATIONS

• Iridium is 6x / 8x Stronger /1200 Degrees 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 A/F Mixture Access = More Power
• Ability to Ignite Lean Mixtures and Difficult to Ignite Fuels
• High Pressure, High Output Race Engines
• Turbo / Supercharged / Nitrous
• Good Resistance to Fouling and Easier Starts

PERFORMANCE FEATURES OF BRISK IRIDIUM RACING SPARK PLUG 

Iridium is 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 that helps direct 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.

BRISK RACING IRIDIUM spark plug Lower Required Supplied Ignition Voltage – is achieved by utilization of optimized diameter spark plug center electrode, along with sharp edges of the cut back ground electrode. This spark plug feature 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. Brisk Iridium Racing 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.

Optimized 1mm diameter Brisk Racing Iridium spark plug iridium center electrode is capable to displace more heat than smaller diameter tips. Brisk Racing Iridium spark plug Cut back ground electrode accumulates less heat, displaces heat more rapidly, and allows for better access of A/F mixture to the spark and easier (less restricted) spread of the flame front immediately after the ignition.
