Spark Plug (Set of 6) - VW/Audi 3.6L VR6 | 101905622-BOS-KT6

Set of 6 Spark Plugs

Generally when one spark plug fails that means the rest will also fail soon. We recommend you change all spark plugs at once. That way a month later you won't be running a cylinder short because one of your other spark plugs failed.
