Just to help those who have this need. Recently acquired my new e-Niro and the above kit was not available via the dealer so I researched myself and found two really good products and providers who were most helpful.
- Titan Covers for boot liner. Laser cut for e-Niro. Perfect.
- Dog Guard ATHAG / Guardsman - https://www.guardsmandogguards.co.uk/product-category/kia/kia-niro-2016-onwards/
