This is a full set of 8 Mishimoto OE-replacement ignition coils for the 99-07 GM Square Style Engine — one per cylinder. Each coil is designed and tested to meet or exceed the factory coil's performance, restoring a strong, consistent spark and clearing up the misfires, rough idle, and hard starts that come from worn or failing coils. Replacing the whole set at once (ideally alongside fresh spark plugs) gives the most even, reliable refresh of the ignition system. Backed by Mishimoto's lifetime warranty.
