If you need oversize jets for the two-barrel carb in later 2002, and don’t want to wait for your BMW dealer to order them, try a VW dealer, since some VW jets will interchange.
VW dealers usually stock a fair assortment of jets and those they don’t have they can usually order and get in a week.
Some dealers insist that you order by part number rather than jet size — more cooperative parts managers will look up the size for you.
If you happen to get stuck with one of the less-helpful variety, VW part #11 1 129 405D is a 120.0 jet and 05 6 129 405A is a 122.5.
