Ignition
Spark
More cylinder pressure (cam, boost, compression) demands more spark energy and a colder plug heat range.
- Spark Plugsignition.spark.spark-plugs
  Cooler heat ranges resist pre-ignition under boost or with aggressive timing.
  Tradeoff: Always sold in 16-packs for the dual-plug HEMI. One bad plug shows up as a single misfire code.

- Ignition Coilsignition.spark.coils
  High-output coils maintain spark energy under boost and at high RPM, where stock coils start to fade.
  Tradeoff: Pricey when bought as a 16-pack. Mostly a worthwhile upgrade only on forced-induction or high-RPM builds.
