Ignition Coils Pack of 8 for Cadillac Buick Lucerne DTS Seville

In this review of the ECCPP Pack of 8 ignition coils, the bottom line is clear: these coils are a practical, budget-friendly replacement for owners of Buick Lucerne and Cadillac DTS/Seville/Deville 2004-2006 who need a full set for long trips or workshop stock. The reviewer found they replicate the original OE design closely, install without special tools, and restore smooth engine operation when faulty coils were causing misfires or rough idle, making them a sensible choice for drivers seeking a complete replacement kit rather than a single coil.

Key Features

• Wide vehicle application: Fits Buick Lucerne and Cadillac DTS, Seville and Deville 2004-2006, so a single kit covers a full set for those models.
• OE designed advantage: Built to mirror original equipment design, which helps ensure the coils plug in and function like the originals when matched correctly.
• Replaces common OE numbers: Compatible with OE references such as D596A, UF564 and C1556, aiding buyers who compare parts before ordering.
• Premium materials: Constructed from higher-grade materials for improved stability and reliability over cheap aftermarket pieces.
• Complete pack convenience: Supplied as a pack of 8, convenient for replacing all coils at once to avoid staggered failures on long drives.

Who It's For

The kit is best for owners and technicians working on Buick Lucerne or Cadillac DTS/Seville/Deville from 2004 to 2006 who want to replace all ignition coils at once, particularly before a long trip or to stock a 4S shop with compatible spare parts. It suits people comfortable verifying OE part numbers and performing basic engine ignition maintenance.

Those who should look elsewhere include drivers with different model years or other makes not listed, and anyone who requires extended durability guarantees from a premium dealer; several users reported mixed longevity, so buyers needing long-term peace of mind may prefer OEM or higher-end branded coils with longer proven lifespans.

Frequently Asked Questions

Will these coils fit my 2005 Cadillac DTS?
Yes, the pack is listed for Cadillac DTS 2004-2006, but compare the OE numbers on your existing coils to the listed references to be certain.

Should I replace all coils at once?
Many installers recommend replacing all coils together because one failed coil can indicate others are aging; the 8-pack makes that practical for the listed models.

Are these coils an exact OEM part?
They are designed to the original OE type and replace common OE numbers, but they are aftermarket parts, so buyers should check fit and expect possible variation in service life.
