It's important to keep your ignition system operating properly to avoid further complications in the future. Here at Turner Motorsport, we offer full ignition service kits if you'e going to overhaul your entire ignition system, and individual components if you've narrowed down your problem already.
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.
