S65 Ignition Service Kit - E9X M3

The Turner Motorsport S65 Ignition Service Kit restores ignition timing and ionic knock-sensing accuracy on the BMW E9X M3 S65 engine. Worn spark plugs alter cylinder electrical resistance, disrupting ionic current knock detection across the ignition coils. Replacing all eight NGK plugs, S65 coils, and applying AGS dielectric boot protector restores precise combustion and knock monitoring.

S65 Ignition Service Kit - E9X M3
$2236.99

The S65 Ignition Service Kit restores ignition performance and cylinder knock-sensing accuracy on the E9X M3 by replacing primary firing components. Because S65 ignition coils utilize ionic current measurement across the spark plug gap to detect engine knock, the ignition system relies on precise electrical resistance from fresh spark plugs. Replacing worn spark plugs and degraded ignition coils restores critical knock monitoring capabilities and maintains correct ignition timing.

  • Application: E9X M3 S65 engine
  • Spark Plugs: Quantity 8 NGK spark plugs
  • Ignition Coils: Quantity 8 S65 ionic knock-sensing ignition coils
  • Chemical Protection: Quantity 1 AGS dielectric boot protector (4-gram packet)

Turner Tip: Apply the AGS dielectric boot protector inside the ignition coil boots during installation to seal out moisture without altering spark plug circuit resistance.

Order the S65 Ignition Service Kit to restore accurate knock sensing and combustion efficiency.
