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-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.

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.
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.
