Spark plugs

It may be difficult to replace the spark plugs. It is recommended that you have the spark plugs replaced by your SUBARU dealer.
The spark plugs should be replaced according to the maintenance schedule in the “Warranty and Maintenance Booklet”.

• When disconnecting the spark plug cables, always grasp the spark plug cap, not the cables.
• Make sure the cables are replaced in the correct order.
