What is this panel called?

[Flooble]

It's the plastic panel that fits over the sill underneath the doors, between the front and rear wheels on an ND model MX5 1.5 SE-L.





But I'm not sure what to call it when searching for a replacement on eBay, salvage sites etc. Sill panel? Side Panel? Side Skirt?

Does anyone have any ideas?

Thanks!

I would say "side skirt"

Thanks, will try that on the search.
