To replace the spark plugs of the Seat Leon, we open the hood, disconnect the side flexible hose from the engine cover and remove it. We cover the throttle body with a rag, unscrew the oil cap and plug the hole with a cloth. Using a screwdriver, we disconnect the connectors of the coils, with a 10mm wrench we unscrew the ground bar, disconnect the coils of the spark plugs marking the exact sequence.

Using compressed air, we clean the spark plug seats and unscrew them with a 16mm socket wrench with an extension, remove the old ones and replace them with new ones after applying a thin layer of grease on the threads. Initially tighten them by hand and finish by tightening with a torque wrench to 25 Nm, reassemble the other components by reversing the operations.
