Thanks Everyone! I think I'm going to order the K7 door sills. Also, I have been looking for the black/chrome "K" emblem for the badge swap but am not sure of the quality of the parts I'm looking at on eBay. Any suggestions??
Welcome to the Cadenza Forums.
I am the owner of the K5 Optima Store, and would be happy to help you find any parts you are looking for, for your Cadenza.
For starters, as others have mentioned, there are no in-channel window visors I have come across for the Cadenza.
In regards to the emblems, we are the North American Distributor of the authentic 3.0K emblems, so you won't have any issues ordering them from us.
Unfortunately, with them being such a popular product, like many other popular products on the market, there are tons of fakes and replicas.
Please feel free to look at some of the 720+ 5-star verified reviews on our site, just on this 1 single product alone.
You can find the 3.0K emblems in black and chrome on our site here: Kia 3.0K Emblems - K5 Optima Store
You can find the K7 Door Scuff Plates on our site here: Kia Cadenza/ K7 OEM LED Lit Door Scuff Plates - K5 Optima Store
Both the emblems we sell, and the door scuff plates are in stock in our store in Los Angeles, CA, and would ship out the same day you ordered them from us online.
You can find a ton of different aftermarket and OEM parts that we sell for the Kia Cadenza on our site here: Kia Cadenza Product Collection - K5 Optima Store
With that being said, if there are any parts you are looking for not listed on our site that you find elsewhere, please note that many times we can get the same parts for you quicker, and many times cheaper as well. So if there is anything you are interested in that you don't see on our site, please feel free to reach out to me or Paul Walton
anytime for assistance.
