What one is the right one from GSF?
What have you searched for? Presumably you're looking on their website?
yeah there are loads of them. but nothing i can see unless im going blind.
Phone them up quote your reg or engine code year and modle and let them do the finding, that's what I do although to be honest with gsf pot luck what actualy turns up sometimes !
make sure you get a Beru or Bosch one.
Will give them a call and ask specifically for a bosch one.
lol even if you ask for a bosch one id be suprised if you actualy got it i ordered beru leads and specificaly asked for them on the phone and ended up with some other make have done this with many other things aswell can somtimes be best to go in to a branch at least then you can see what your getting before you actualy buy it avoiding having to send it back again.
