Ignition Coil for 2003-2008 Jaguar S-Type & More - ThunderSpark 921-92084

Keep every cylinder firing with the ThunderSpark Ignition Coil 921-92084, a direct-fit replacement for the 2003-2008 Jaguar S-TYPE and the 2002-2008 Jaguar X-TYPE. An ignition coil steps up the vehicle's low battery voltage into the high-voltage charge needed to jump the spark plug gap and ignite the air-fuel mixture in the cylinder, so a weak or failed coil is a common cause of ignition trouble on these applications.

• Core job: Converts the system's low voltage into the high-voltage output that fires the spark plug on its cylinder.
• Signs this part may need replacing: Engine misfire, rough idle, hesitation, hard starting, reduced fuel economy, or an illuminated check engine light. If a failed ignition coil is the cause of these symptoms, this replaces it.
• Direct-fit installation: Installs in place of the original coil on the listed applications.

Because a misfire can have several causes, diagnose the source before replacing parts. See the "Vehicles it fits" section to confirm the fit for your Jaguar.
