Frequently Asked Questions: OE 16318161-00
When would this plate be sent out?
Delivery time is confirmed with your quote. Because this is a long panel, pick a delivery day when somebody can be at the address to take it in. Check the fitment table on this page against your own car first, so the wait is not spent on the wrong plate. The shipping cost is confirmed with your quote.
This plate is long. How does a part that size get delivered?
This one is too long for a standard parcel network, so it goes out on an oversize service instead. The packaging details are shown on this page. Length is what settles the carrier here, not weight. Make sure there is somewhere to lay the panel down flat when it arrives, and that whoever takes it in can manage a board of that size. Do not book it to an address where nobody can receive a long consignment.
What is this guard plate made from?
This guard plate is metal. Thickness and finish are not given, so we will not guess at either for you. What the material does change is handling. The edges of a panel this size are sharp, so wear gloves when you unwrap it and keep it flat rather than propped against a wall. The plate is supplied new. Read the fitment table on this page before you unwrap anything at all.
Whereabouts on the car does this plate fit?
This one mounts on the underbody of the BYD Seal 05 DM-i, so it is reached from below with the car raised rather than from the engine bay or the boot. That is a location note only. We publish no fixings, no torque figures and no fitting sequence for it, and nothing of that sort should be read into the listing. If you are matching it to a plate already off the car, compare the OE number 16318161-00 with the marking on the old one and check the fitment table here.
Why is there no second version of this plate to choose from?
There is one version of this plate on the site, the genuine BYD part. No aftermarket alternative has been sourced against 16318161-00, so there is nothing to compare it with on the page and no second tier to select. On parts where we offer both, an Original/Genuine option and an Aftermarket option appear together and the choice is yours. If you want us to look for another source for this application, use the quote route on this page and give us the model and year you are working on.
