Setup, Compatibility & Care
Before installation, ensure the engine is completely cool to avoid damaging the cylinder head threads. Verify the gap of the plug using a gap tool; although factory set, shipping can sometimes alter the setting. When installing, thread the plug by hand for the first few turns to prevent cross-threading, then use a torque wrench to reach the manufacturer’s specified tightening value. Because this plug uses a gasket seat, ensure the old gasket is removed before installing the new unit. Clean the area around the spark plug well with compressed air before removal to prevent debris from entering the combustion chamber.
