Spark plugs J Replacing the spark plugs Your vehicle is equipped with platinum-tipped spark plugs. It is not necessary to replace the platinum-tipped spark plugs as frequently as the conventional type spark plugs since they will last much longer.

If replacement is required, see your SUBARU dealer for servicing. J Recommended spark plugs PFR5B-11 (NGK), RC10PYP4A (Champion) 10-18
