How to replace the spark plugs on Buick Regal?

Beginning the Spark Plug replacement process requires turning off the Ignition Switch followed by disassembly of the fuel injector sight shield. Start by removing the engine-based spark plugs along with disconnecting their Spark Plug Wires from the engine. A proper Spark Plug gap measurement should be taken before installation to verify the required specifications. Make adjustments to achieve the necessary gap. The installation torque for new cylinders should reach 27 nm (20 lb ft) but existing cylinders require a torque of 15 nm (11 lb ft). Plug the spark wires back in place before placing back the fuel injector shield.
