Frequently Asked Questions: OE 16746640-00
The number on my old horn does not match 16746640-00, what now?
If the number on your old horn is not 16746640-00, check whether it shows SFH-3721010-D1, since that is the only other reference given for this part. Beyond that, do not try to match by number alone. Find the model and the model year as written on your registration document, and use those to check you are ordering the right horn for your Bao 8 or Bao 5. That detail matters more here than the code stamped on the housing you are holding.
How soon will this horn arrive once I order it?
Delivery time is confirmed with your quote. If you want to confirm exact timing for your address, use the quote route on this page. The shipping cost is confirmed with your quote. Before you order, check the number on your old part against OE 16746640-00. If anything about the timing matters for a booked repair, ask through the quote route on this page.
Where on the car does this horn actually sit?
Fitted in the engine bay, this horn is made of plastic. For the exact mounting position on your car, take a look at the photographs on this page, since seeing where it sits on the Bao 8 or Bao 5 tells you more than a written description can. That is the quickest way to see exactly where it fits before you order.
