Brisk Spark plugs for the new 2011 FORD 5.0L, V8 engine are: Stock Heat range: ROR15LGS, RR15YC-1 One step colder: ROR14LGS (N/A app. only), RR14YS (projected tip- low boost forced induction app.), RR14S (non-projected tip-good for nitrous or forced induction) Two step colder: RR12S (non-projected tip) – High Compression, Forced Induction and/or Nitrous Three step colder: RR10S (non-projected tip) - High Compression, Forced Induction and/or Nitrous.
Brisk Silver Racing plugs have a better ignitability than conventional performance spark plugs, and offer better performance and reliability in high boost, nitrous or high compression applications. Silver is an element with the most free electrons, and is the best electrical and thermal (heat) conductor of all metals! Better than gold, copper ...and many times better than Iridium. The Brisk Silver Racing plugs have a fine wire center electrode (not just the tip), which gives more room for insulator between the center electrode and spark plug shell. More insulation results in a durable spark plug with high dielectric strength - the most important spark plug parameter in forced induction applications. Brisk Silver Racing spark plugs have helped Tim Lynch and Steve Petty to keep the A/F mixture lit and set 4 New World Records since they started using them in their extreme 3,000+Hp 6.66sec @ 223.5mph Twin Turbo 10.5 Outlaw Mustang, and can do the same for you. In street applications, the greatest advantage is a powerfull spark, improved performance, low ignition voltage requirements, excellent heat dissipation at full load and excellent anti-fouling resistance under light load operation. Brisk Silver Racing Spark Plugs are available for all makes and models, so order yours today!

Advantages of Brisk High Performance & Racing Spark Plugs
Unique And Patented High Performance Spark Plug Designs
Higher output, better throttle response and acceleration are achieved through better fuel energy utilization. This in turn also lowers the exhaust emission.
Completely New and Patented High Performance Spark Plug Gap Configurations
Brisk's design provides an unrestricted and more spontaneous spread of the flame front which is achieved by:
Retracted ground electrode- Unlike conventional spark plugs, where the discharge is constrained by the ground electrode, Brisk Premium Spark Plugs utilize a design where the ground electrode is retracted so the spark discharge occurs at the very tip of the spark plug.
The ground electrode design of the traditional spark plug restricts the natural spherical expansion pattern of the flame front Brisk Premium Spark Plugs utilize surface spark discharge along with retracted ground electrode designed to ensure maximum spark exposure and unrestricted flame front propagation
Utilizing hotter semi-surface spark discharge- It is easier (takes less energy) for a spark to glide along the surface of the insulator than to break through the air gap. Brisk Premium Spark Plugs take advantage of this feature in its design. Almost 2/3 of the spark travel between the electrodes is along the surface of the insulator. The length of the spark discharge is maximized with only a slight increase in the required supplied ignition energy. The higher voltage buildup at the center electrode before the spark-over results in delivering more spark energy into the combustion chamber. However, this spark plug requires a sound ignition system (in good condition) for proper operation.
Utilizing a special ground electrode design- The spark discharge can occur in almost 360 degree perimeter at the place with the most optimal air fuel composition; which is where the ionization of the molecule is most easily achieved. This special feature ensures that the spark occurs at the best possible place for ignition, unlike in the conventional spark plug design where the spark always occurs in the same confined place. Since the air fuel mixture inside the combustion chamber is not homogenous (has different concentration at different places) this results in faster and better ignition of each ignition cycle. In addition, there is no need for indexing of the spark plugs since the plug is symmetrical and there is no ground electrode restricting the access of the air fuel mixture.
Spark Plug Gap is Close to the Center of the Combustion Chamber
Shifting the spark gap deeper inside the combustion chamber provides better access of the air fuel mixture to the point of ignition. Since the flame front propagates evenly in all directions the best place for ignition is in the center of the combustion chamber. The compact design of the spark gap minimizes turbulence and therefore increases the volumetric flow.
Spark Plug Integrated High Performance Ground Electrode
The massive ground electrode is the integrated part of the spark plug shell which provides superior heat removal from the active part of the spark plug, improving the resistance to pre-ignition and electrode burn-off.
