Frequently Asked Questions
Should I replace all my ignition coils at the same time?
It’s a smart move to replace all ignition coils at once. When one coil fails, the others aren’t far behind. Installing a full ignition coil pack saves you future headaches and ensures your engine runs smoothly.
What is the difference between aftermarket and OEM car ignition coils?
Honestly, the biggest difference is the price. While OEMs are made by the same company that made the original parts for your vehicle, our parts all meet or exceed OEM specifications. Our aftermarket ignition coils deliver top performance without that dealership markup.
What are the signs of a bad ignition coil?
The signs of bad ignition coils can be anything from engine misfires to rough idling or a drop in gas mileage.
