Step 3: Prepare the New Spark Plug

Check the gap on the new spark plug using a gap tool. The correct gap for the 2012 Arctic Cat 550I should be set according to the manufacturer's specifications. Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the engine.
