To replace the spark plugs on the Honda Civil, 8 detach the ignition connectors and return the ignition coils. Then spin the spark plugs by using the candle-key. When the spark plug is in the ignition, clear it with a candle cleaner. If necessary, install new candles. On the rubber part of the candle, do a small amount of block blocking the threaded connection and put it in the head of the cylinders from the hand to the point-blank range. Then it will be delayed with 25 Nm. Collect everything in reverse sequence. Spark plugs (K20Z): NGK-IZFR6K11; DENSO-SKJ20DR-M11.
