CAUTION: All spark plugs installed on an engine, must be of the same heat range.

Spark plug:
CHAMPION: flC10YC4 (Alternate)
CHAMPION: RC8YC4
NGK: BKR6E-11
NIPPONDENSO: K20PR-U11

1. #1 SPARK PLUG




1. Disconnect battery ground cable.
2. Remove air intake duct and resonator chamber.




1. Remove bolt which installs air intake duct on the front side of body.




2. Remove bolt which installs air intake duct on body.




3. Remove air intake duct as a unit.




4. Remove resonator chamber.




3. Remove #1 spark plug cord by pulling boot, not cord itself.




4. Remove spark plug with the spark plug socket.
5. Installation is in the reverse order of removal.

Tightening torque (Spark plug):
20.6 ± 2.9 N.m (2.10 ± 0.30 kg.m, 15 ± 22 ft.lb)

CAUTION: The above torque should be only applied to new spark plugs without oil on their threads. In case their threads are lubricated, the torque should be reduced by approximately 1/3 of the specified torque in order to avoid over-stressing.

2. #2 SPARK PLUG




1. Disconnect battery ground cable.




2. Remove #2 spark plug cord by pulling boot, not cord itself.




3. Remove spark plug with the spark plug socket.
4. Installation is in the reverse order of removal.

Tightening torque (Spark plug):
20.6 ± 2.9 N.m (2.10 ± 0.30 kg.m, 15.2 ± 2.2 ft.lb)

CAUTION: The above torque should be only applied to new spark plugs without oil on their threads. In case their threads are lubricated, the torque should be reduced by approximately 1/3 of the specified torque in order to avoid over-stressing.

3. #3 SPARK PLUG




1. Disconnect battery ground cable.
2. Remove air intake duct and air chamber.




1. Remove bolt which installs air intake duct on the front side of body.




2. Remove bolt which installs air intake duct on body.




3. Remove air intake duct as a unit.




4. Remove resonator chamber.




3. Remove #3 spark plug cord by pulling boot, not cord itself.




4. Remove spark plug with the spark plug socket.
5. Installation is in the reverse order of removal.

Tightening torque (Spark plug):
20.6 ± 2.9 N.m (2. 1 ± 0.30 kg.m, 15.2 ± 2.2 ft.lb)

CAUTION: The above torque should be only applied to new spark plugs without oil on their threads. In case their threads are lubricated, the torque should be reduced by approximately 1/3 of the specified torque in order to avoid over-stressing.

4. #4 SPARK PLUG




1. Disconnect battery ground cable.




2. Disconnect washer motor connector.
3. Disconnect rear window glass washer hose from washer motor, then plug connection with a suitable cap.




4. Remove the two bolts which hold the washer tank, then take the tank away from the working area.




5. Remove #4 spark plug cord by pulling boot, not cord itself.




6. Remove spark plug with the spark plug socket.
7. Installation is in the reverse order of removal.

Tightening torque (Spark plug):
20.6 ± 2.9 N.m (2.1 ± 0.30 kg.m, 15.2 ± 2.2 ft.lb)

CAUTION: The above torque should be only applied to new spark plugs without oil on their threads. In case their threads are lubricated, the torque should be reduced by approximately 1/3 of the specified torque in order to avoid over-stressing.
