The Brisk RR14YS spark plugs have a colder heat range compared to the stock spark plugs. Recommended for STOCK 1.6L/2.0L, 2.3L EcoBoost cars. With projected tip design.

Spark Plug Heat Range

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-ignition 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.

Key Benefits and Applications of Brisk Silver Racing Spark Plugs

As expected

First, FSWERKS always has goods out and delivered promptly. These plugs replaced plugs that still had less than 30k on them but the acceleration seems a bit more responsive and gas mileage may be up just a tick.

Excellent product

FSWerks comes through again. I ordered a set of plugs and had them in my hands in just a few days. I got them installed in about 30 minutes and was back on the road in no time. I will keep coming back to FSWerks, because they know their craft, they know their products and best of all know what their customers want most.
