Mishimoto Ignition Coils 6 Pack 04-09 Cadillac CTS V6

Mishimoto Ignition Coils supply consistent high-voltage spark to restore ignition reliability and reduce misfires in 2004–2009 Cadillac CTS V6 engines.

This 6-pack of replacement ignition coils is intended to address the common maintenance need of weak spark, which can cause misfiring, rough idle, and degraded engine performance. Installing matched coils restores ignition consistency across all cylinders and helps return the engine to its expected running condition before pursuing any power modifications.

• Application: 6-pack replacement ignition coils for 2004–2009 Cadillac CTS with V6 engine — direct-fit service parts to replace worn or failing units.
• Primary function: Deliver reliable high-voltage spark to each cylinder to minimize misfires and improve combustion stability.
• Maintenance value: Ensures ignition system readiness prior to performance upgrades and supports predictable drivability during tuning or forced induction work.
• Brand: Mishimoto — designed and supplied by a specialist in automotive thermal and engine-related components.

Installation of a full set of coils is recommended when diagnosing intermittent misfire codes or when multiple cylinders exhibit weak spark symptoms. Replacing all coils at once ensures uniform electrical characteristics and helps isolate ignition-related issues from fuel, air, or compression problems.

Benefits at a glance: improved ignition consistency, reduced rough idle, cleaner combustion across cylinders, and a reliable baseline for further engine performance work.
