Spark Plug Check And Cleaning: Notes

WARNING: This page is about a different car, the 2009 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

Required Special Tool

MB992273: Spark Plug Brush

CAUTION:

Never attempt to adjust the gap of the iridium plug.
Do not attempt to clean the iridium plug using a wire brush because it may result in damage to the electrode. When the iridium plug is cleaned, use a plug cleaner, sand blast type, or special tool MB992273.

NOTE: Obey the maintenance interval of the vehicle for the spark plug replacement. If the plug gap and insulation resistance are normal, check the plug state and clean it if necessary.
