Frequently Asked Questions

How many ignition coils come in the pack?
Each pack contains 8 ACDelco D514A ignition coils.

Will this fit my Silverado, Sierra, Tahoe or Escalade?
Fitment varies by year and engine. Check the part number against your original coil or contact us with your year, make, model and engine size.

Should I replace all the coils at once?
Many owners replace the full set so every cylinder has a fresh, matched coil, which can help prevent repeat misfires. A single failing coil can also be replaced on its own.
