For more information, visit www.P65warnings.ca.gov.The APR Ignition Coils (MS100252) are a high-performance, direct plug-and-play upgrade designed specifically for the Porsche 9A2 engine family found in the 911 (991.2/992) and 718 Boxster/Cayman. While many enthusiasts attempt to "upgrade" by using coils from higher-output Porsche models, APR’s testing confirms those factory units rarely provide a true increase in energy. In contrast, APR coils are engineered to deliver up to 17% more energy output than stock, ensuring a stronger, more consistent spark even under the high cylinder pressures of tuned or high-boost applications.
To achieve this, APR increased the diameter of the copper windings to reduce electrical resistance and utilized larger, higher-strength neodymium magnets. The internal voltage regulation is meticulously managed through Zener diodes and an upgraded silicon steel shield, minimizing energy loss and optimizing the spark across the entire RPM range. Finished in APR’s iconic Red housing, these coils provide a significant performance benefit alongside a striking visual upgrade for your engine bay.
Features:
- Increased Spark Energy: Delivers up to 17% more energy output than the factory Porsche coils.
- Advanced Engineering: Features larger copper windings and neodymium magnets for maximum efficiency and reduced resistance.
- Better Combustion: Promotes a cleaner and more complete fuel burn, improving throttle response and idling stability.
- Performance Aesthetics: Signature red housing with the APR logo for a customized, high-end look.
- Rigorous Quality Control: Batch tested for over 73 hours (15+ million firings) in open-circuit setups to ensure absolute reliability.
- Direct Fitment: True plug-and-play installation—no tools or modifications required beyond the standard replacement process.
- Peace of Mind: Backed by a 1-year, unlimited-mile direct-replacement warranty.
