ThunderSpark Ignition Coil P/N:921-2131

Deliver a strong, consistent spark to keep combustion firing cleanly with the ThunderSpark Ignition Coil 921-2131. It drops in as a direct-fit replacement for the 2006-2008 Suzuki Grand Vitara and the 2007-2009 Suzuki SX4, transforming the vehicle's low battery voltage into the high-voltage pulse needed to jump the spark plug gap and ignite the air-fuel mixture in the cylinder.

• Core job: steps up primary voltage into the high-voltage output that fires the spark plug for reliable ignition.
• Direct-fit application: serves as a direct-fit replacement for the listed Suzuki applications.
• Signs this part may need replacing: engine misfires, rough idle, hesitation on acceleration, hard starting, or an illuminated check engine light.
• Diagnose first: because a misfire can have several causes, confirm the coil is the source before replacing it.

If a failed ignition coil is the cause of your misfire, this unit replaces it to restore proper spark delivery on the covered engines.
