Symptoms to look for

A misfire code on one cylinder, or stumbling under acceleration. On a full-size car, turbocharged and naturally aspirated cars share a badge and little else in this group.

Buying OEM, briefly

• Factory warranty. Genuine ignition coils carry GM coverage aftermarket cannot match.
• Dealer parts, not dealer prices. Compare our ignition coils pricing against a counter quote.
• Genuine GM only. Every ignition coils listing carries the original factory part number.
• Fitment checked by a person. Send the VIN and we verify the ignition coils before the box leaves.
• Central shipping origin. Dallas keeps ignition coils transit times short nationwide.

Ordering correctly

Factory parts are built to the tolerances the vehicle was engineered around, not copied from a worn sample. A photo is rarely enough to order from. The VIN takes seconds and removes the guesswork. Freight is quoted at what it actually costs, not inflated to subsidize a headline discount.
