Spark Plug (Set of 8) - VW/Audi / 4.2L V8 / B6 & B7 S4 / C5 RS6 / Allroad / D2 A8 / Touareg | 101905615A-BOS-KT8

Set of 8 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.  


Bosch is the OEM Supplier for VW/Audi
