This Kit Contains: 6-Delphi Ignition Coils GN10571-12B1 BMW OE #: 12138616153 6-NGK Spark Plugs 5987 (LZFR6AP-11GS) BMW OE #: 12120037663 Sold as a set w/ a 2 year warranty FREE USPS PRIORITY SHIPPING Delphi Direct Ignition Coil - (Coil on Plug) Delphi ignition coils feature precise spark timing response for increased fuel economy and faster crank-to-run. The ignition coils provide accurate electrical energy to create a voltage potential at the spark plug, providing for superior engine performance that adjusts to driving and environment conditions. Plus, like all Delphi ignition system components, they enable engine management systems to maintain tighter control over emissions, economy and performance. Features and Benefits: Improved dwell accuracy decreases module and coil temperatures for greater reliability Noise abatement material between laminations reduces audible coil noise Cassettes have improved primary connector for greater ease of assembly compared to designs with one connector for each coil Lower primary inductance provides high-speed performance Early and precise electronic spark timing helps improve fuel economy and provides faster crank-to-run Higher energy delivered to combustible mixture provides cleaner combustion to help manufacturers meet on-board diagnostics (OBD II) requirements Direct connection to spark plugs (via small boot) eliminates spark plug wires Composite iron coils provide programmable energy Coil per cylinder dwell overlap electronics deliver better high speed performance and better heat dissipation compared to some conventional technologies Coil per cylinder ramp and fire electronics decrease power dissipation and increase efficiency NGK Laser Platinum Spark Plug NGK Laser Platinum spark plugs provide high ignitability and longer service life. Dual platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions. The platinum disc welded to backside of ground electrode provides long life, faster starts and quicker acceleration. Laser Platinum spark plugs provide high ignitability and longer service life. Features and Benefits: Laser welded Platinum center electrode tip Platinum disc welded to backside of ground electrode provides long life Trivalent Metal Plating provides superior anti-corrosion and anti-seizing properties Faster starts and quicker acceleration Better fuel economy and lower emissions Best Platinum spark plug available Original Equipment Manufacturer approved design
