The Brisk RR14S spark plugs have a colder heat range compared to the stock spark plugs and a non-projected tip for an additional decrease in spark plug firing tip temperature. For modified 1.6L/2.0L, 2.3L & 3.5L EcoBoost. With non-projected tip

Spark Plug Heat Range

In identical spark plug types, the difference from one heat range to the next is the ability to remove approximately 70°C to 100°C from the spark plug center electrode and ceramic tip. A projected style spark plug firing tip temperature is increased by about 15°C to 25°C.

Heat range is the measure of how fast the spark plug tip dissipates combustion heat. It must do this in a precise and controlled manner so the spark plug will:

  • Stay cool enough to avoid pre-ingniton and/or electrode destruction due to detonation.
  • Run hot enough to burn off combustion deposits that would otherwise collect on the insulator tip and cause fouling that results in misfire.
  • Adapt to specific engine characteristics and widely varying driving/load conditions.

Brisk racing spark plugs the best

My first experience showed I selected the wrong plug. Once I selected the RR14S and gapped @ .028 with the FRPP tune the car instantly showed a response. Power was already there its just more responsive power
