3. Remove the spark plugs and screw in new ones. The spark plugs included in the standard equipment of the engines of the cars in question are multi-electrode, the gap in these spark plugs is not adjustable. If single-electrode spark plugs are installed, then set the gap by checking it with a flat or round feeler gauge (see photo).









4. Before installing the spark plugs, make sure the spark plug threads and insulator are clean. Screw in the spark plug using a piece of rubber hose to screw in the spark plugs without skewing. Remove the rubber hose and tighten the spark plug (see photo). Wrap up the remaining candles.



5. Connect the high-voltage wires in the same order (check their condition first), install the removed parts.
