Nissan Serena Spark Plugs Malaysia — MR20DD
Serena C27 MR20DD: iridium spark plugs, replace every 60,000 km, 4 plugs. Direct injection engine — iridium mandatory. Quiet MPV cabin makes plug condition very noticeable — even mild misfires felt by passengers. Don't delay past 60,000 km — worn plugs in a DI engine increase carbon deposit rate.
