The kit is only about 1 year old but the aftercooler is about 5 months old. The kit has newer bigger 36# injectors. The kit is complete besides the ECU reprogram or chip. The kit fits OBD1 and OBD2. Because the Aftercooler replaces the traction-control on OBD2. The kit is still in car if wanting to look at if live in the east coast area. The kit was installed by 15 yr. BMW tech. The kit will be taken off by same BMW tech. All parts will be taken off! Complete kit. He can also install for you at an additional price. This whole kit new is 7800. So make resonable offer
