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.
