[Javigo1971]

Ok so 5 simple questions. ..
1..where can I get a 4.8is flare kit that fits my 2004 x5 4.4is

2..is there a way I can connect my usb memory stick some where. ..

3...if my passenger door doesn't open with the key fob lock stays down door won't open from outside only from the inside. ...is that the handle carrier. .lock actuator or handle key lock ...kind of confuse on that one..

4... can I lower my x5 couple of inches once I put the 20" wheels on...

5...my passenger window opens only with its own door switch. ..not with the drivers main one that means that the driver main switch is bad or what??
