Fully Enclosed Air Deflector for BYD Dolphin, OE 13277338-00

The difference is in finish and fit precision rather than function. Original or Genuine parts carry BYD branding and match the factory shape exactly, while Aftermarket versions are built to the same OE number but from a separate manufacturer. Have a look at the photographs on this page before ordering, since they show the panel shape, mounting points and finish so you can judge which tier suits your car. If your old deflector is cracked rather than missing, compare it against the images to confirm the profile matches.

If the number stamped on your old deflector does not match 13277338-00, do not assume this is a straight swap on looks alone. Check the model and the model year as shown on your registration document and compare those against what this part is listed for, since that is the detail that confirms fitment rather than the shape of the plastic in your hand. Use that document before you order, not the old part's appearance.

This deflector is a light plastic moulding, and the packaging details are shown on this page rather than described here. Before you order, open the fitment table on this page and check it lists your Dolphin, since getting the fitment wrong is best avoided before a parcel this size is sent. The listed OE number is 13277338-00, also shown as EM2E-5302490A, so match that number against your old part before you commit to the order.

It is made of black plastic, moulded to sit fully enclosed in the engine bay rather than as a flat sheet cut to shape. That means it only works as a direct match for the mounting points on this BYD Dolphin, not as a generic panel trimmed to fit. If you are not certain the shape you have matches the OE number 13277338-00, use the quote route on this page and a member of staff will confirm it against your vehicle before you order.

No painting is needed here, since this deflector is finished in black plastic rather than supplied bare for spraying. If you want to double check that against your own records, this part is also listed under the reference EM2E-5302490A, which is worth searching against your own paperwork or a parts catalogue to confirm you are looking at the same item before you order. Sitting in the engine bay out of sight, colour match to the bodywork is not something you need to consider here.

Fitted in the engine bay, this deflector directs airflow around components under the bonnet rather than sitting anywhere on the visible bodywork. Because it is described as fully enclosed, it is designed to close off a specific gap rather than sit loosely, so before you order take a look at the side, the exact position and the fixings on your own car to be sure this matches the same area as the panel you are removing. That check matters more than the part's appearance from a distance.
