This is a Mishimoto OE-replacement ignition coil for the 85-05 Buick Century V6, sold individually. It's designed and tested to meet or exceed the factory coil's performance, so it restores a strong, consistent spark and clears up the misfires, rough idle, and hard starts that come from a worn or failing coil. Pair it with fresh spark plugs for a clean refresh of the ignition system. Backed by Mishimoto's lifetime warranty.
