Keep every cylinder firing crisply with the SKP Ignition Coil (SKIC346), a direct-fit replacement for the 1999-2009 and 2011 Porsche 911, the 1997-2008 Porsche Boxster, and the 2006-2008 Porsche Cayman. An ignition coil steps up the vehicle’s low primary voltage into the high-voltage pulse needed to jump the spark plug gap and ignite the air-fuel mixture, so a worn or failed coil can leave a cylinder starved for spark.
- Core job: transforms battery-level primary voltage into the high-voltage output that fires the spark plug.
- Direct-fit: installs as a replacement on the listed Porsche applications.
- Signs this part may need replacing: misfires, rough idle, hesitation, hard starting, or an illuminated check engine light — diagnose the cause before replacing, since these symptoms can have other sources.
If a failed ignition coil is the cause of your misfire, this SKP unit replaces it. Because coils commonly fail one at a time, inspect the others and the related spark plugs so the repair holds.
Interchange: Manufacturer part number SKIC346.
