To find the correct spark plug gap for your specific Buick Park Avenue, you must consult your owner's manual. The information will be in the maintenance section, often near the specifications for fluids and other maintenance items.
Alternatively, you can look up the information online using your vehicle's year, make, model, and engine size. Many automotive parts websites will have this information in their repair databases. However, always double-check against your owner's manual as the most reliable source.
