Spark plugs are used on Ford Fusion car engines with a working volume of 1.25–1.6 liters NGK ITR6F13 (Motorcraft AGFS22IPG). As a substitute for engines with a working volume of 1.25–1.6 liters, spark plugs can be used BRISK RR15YC1 or DENCO PT16VR13. The gap between the electrodes of the candles is 0.7–0.8 mm.
1. Remove the air filter housing (see «Checking and replacing the air filter element»).
2. Remove the tip of the high voltage wire from the spark plug being replaced.
3. Blow out the spark plug wells with compressed air to prevent dirt from entering the engine cylinder when the spark plug is removed.
4. Remove spark plug..
5.... and remove it from the candle well.
Note. Inspect the candle and evaluate its condition by appearance (see «Diagnostics of the engine condition by the appearance of spark plugs»).
6. Use a round feeler gauge to check the gap between the electrodes of the spark plug. It should be 0.7–0.8 mm.
7. If the gap differs from the specified value, adjust it by bending the side electrode.
Attention! Adjust the gap only by bending the side electrode. Any bending of the center electrode will break the spark plug insulator.
8. When installing spark plugs, screw them in first by hand (wrench without collar), and then tighten with a wrench.
