Cadillac Escalade Ignition Coils & Parts

Ignition coils are among the principal components of every gasoline engine, and those installed under the hood of your Cadillac Escalade are no exception. The coil is the very part responsible for creating a high-voltage impulse that goes to the plug and turns into a spark. Repeating this cycle several thousand times per minute, each coil is subject to high loads and tends to fail over time. Although it can endure quite a long mileage, soon or late, its performance will drop, which will result in misfiring in the corresponding cylinders and lots of related issues.

Depending on the vehicle and its model year, several coils can be joined in a single ignition module controlled by the ECU, or your SUV may have eight separate coils, one connected to each plug through a special boot. Essentially, each coil includes the primary and secondary winding, for low and high voltage, respectively, and when it comes to their longevity, much depends on their isolation, heat resistance, and overall quality. In our collection of Cadillac Escalade ignition coils, you will find a lot of beneficial offerings whose quality complies with the highest standards.
