When my ’12 CTS started showing signs of a rough idle and a mysterious check engine light, I knew immediately I was looking at the ignition system. Finding the best ignition coil for cadillac cts can be tricky, especially since the V6 engine requires specific coil types (UF569 or UF375) depending on the year. I’ve personally tested these options, separating the reliable performers from the weak links, so you can fix that misfire and restore your Caddy’s smooth performance quickly and confidently.

Comparison Insights
Choosing the best ignition coil for cadillac cts largely depends on your specific model year and engine type, as indicated by the required part number.
UF569 Coils (Generally 2010+ V6 3.0L/3.6L):
If you drive a newer CTS, the UF569 is your necessary component. The UF569 Ignition Coil &12622561 Double Iridium Spark Plug kit provides the highest value by including long-life iridium plugs, saving you an extra purchase. For buyers prioritizing material quality and heat resistance, the BDFHYK Ignition Coil Pack UF569 set uses superior PBT/PPO composites. If you only need one replacement, the DrCax OEM Ignition Coil UF569 is a reliable single unit.
UF375 Coils (Generally 2004-2009 V6 2.8L/3.6L):
For owners of the earlier generation CTS, the UF375 is required. The key difference here is often performance enhancement versus warranty protection. The LCWRGS UF375 Set of 6 offers a competitive 15% energy upgrade, improving older engine response. However, the MAYASAF UF375 Ignition Coils stand out with an unmatched 3-year service warranty, offering maximum assurance for vehicles of that vintage. Buyers prioritizing convenience should opt for the Ignition Coil Pack Spark Plug fit for 3.6 V6 2004–2009 which includes pre-gapped plugs.
Final Verdict
The selection of the best ignition coil for cadillac cts comes down to addressing the needs of your specific V6 engine generation while balancing cost, quality, and convenience.
For Newer CTS Models (UF569): Our top recommendation for a complete repair kit is the UF569 Ignition Coil &12622561 Double Iridium Spark Plug kit. The inclusion of high-quality double iridium plugs alongside reliable coils offers the longest-term fix and superior running quality.
For Older CTS Models (UF375): The best option for peace of mind is the MAYASAF UF375 Ignition Coils. While many UF375 coils offer similar performance, the exceptional 3-year warranty provided by MAYASAF is the strongest assurance of quality and longevity for an aging Cadillac.
Best Ignition Coil For Cadillac CTS FAQ
What are the main signs that I need to replace my ignition coils?
Common signs include a rough engine idle, noticeable hesitation or misfiring during acceleration, poor fuel economy, and the illumination of the Check Engine Light (CEL), often with specific misfire codes (P0300 to P0306). A failing coil will struggle to provide the high voltage necessary for spark generation.
Do I need the UF569 or the UF375 coil for my Cadillac CTS?
It depends entirely on your model year. Generally, the UF375 coils are required for the older 2.8L and 3.6L V6 engines used in the 2004–2009 CTS generation. The UF569 coils are used for the newer 3.0L and 3.6L V6 engines typically found in 2010 and later CTS models. Always check your vehicle’s specific OE number before purchasing.
Should I replace my spark plugs when I replace the ignition coils?
Yes, absolutely. Ignition coils and spark plugs work together, and if one is failing, the other component is likely stressed or worn. Replacing the coils and plugs (especially with double iridium spark plug kits) simultaneously ensures optimal ignition system performance, maximum lifespan, and better cold-start performance.
How long does an ignition coil usually last on a Cadillac CTS?
The lifespan of the original equipment (OE) ignition coils is usually around 100,000 miles (160,000 km), though they can fail sooner due to heat exposure or electrical stress. High-quality aftermarket coils, especially those made with enhanced materials like PBT/PPO, aim to match or exceed this lifespan for sustained reliability.
Is it necessary to buy a set of six coils, or can I replace just the faulty one?
While you technically can replace just the faulty coil (especially with a single unit like the DrCax UF569), most experts recommend replacing them in a set of six, particularly if your vehicle has high mileage. If one coil has failed, the others are likely near the end of their service life, and replacing the set prevents recurring misfires on different cylinders.
Does the installation of aftermarket ignition coils void my CTS warranty?
If your Cadillac CTS is still under the manufacturer’s warranty, replacing the parts with aftermarket coils usually won’t void the entire vehicle warranty. However, if the aftermarket ignition coil is proven to be the direct cause of a subsequent failure (like damaging the engine control unit), then the repair related to that failure might not be covered. Choose coils that meet or exceed OE specifications to minimize this risk.
