SKU: OEM-079121131BB-079121131BC


NOTE: THIS PRODUCT IS FOR THE UPDATED COOLANT PIPES ONLY!!! If you are interested in purchasing the entire Hitachi Alternator Upgrade Kit that includes the alternator, please go back one section and add that product to your cart.

Due to their high failure rate, the re-manufactured OEM alternator from Delphi that came on all 04 B6 S4s and early 05 B6 S4s is NO longer available from Audi. However, JHM now sells a complete upgrade for the Delphi equipped cars that allows them to run the better Hitachi alternator that came on late 05 B6-S4s and all B7-S4s.

This partial upgrade kit includes the coolant pipes to make the conversion to the Hitachi Alternator smooth. All you need to do is cut the lower coolant hose to the shorter length required by the pipes in this kit.

Due to current demand for these pipes, orders will ship in 2 - 5 days from the time they are placed.

2004 and early 2005 B6-S4s and allroad w 4.2l V8 (Manual or Automatic Transmission, Fits both). Audi doesn't have a specific VIN split, so you must make sure your alternator says Delphi on it. The Delphi units also have a black plastic cover on the back and are larger than the Hitachi. The newer Hitachi alternators say Hitachi on it and they look like the picture on this product page.
