i just read more of the item, and they do mention that they have new filters. in the part where it says "service parts fitted" it mentions that they have new filters and new o-rings that will be fitted before dispatch.
but in your opinion, they will fit? i looked up the fuel injector part IDs on
http://www.RealOEM.com but couldn't match either my injectors, or the 318i injectors to the IDs they gave, so i wasn't sure.
