For a 2013 Mercury Pro XS 175 HP outboard engine Model # 1175P73EY. I received a set of spark plugs for this Mercury Pro XS 175, their particular type are NGK 1ZFR5J. I know the correct number would be NGK IZFR6J. Would it be bad to install and run the NGK IZFR5J plugs?
do not put 5js in it, yes bad

DEFINITELY obtain the correct IZFR6J Spark Plugs (do NOT run 5J's).
