When I bought my used 2015 JKU I noticed there were a couple spots on the heatsink that were clearly damaged by rocks or other road debris who found their way through the world. famous 7 slots. Fast forward and I bought these trim pieces. they fit well and are easy to put on. I've seen inserts in the past that only attach to tape or clips, they can do both. Nice gesture. I'm sure this will help avoid additional cooling fins in the future. Besides, they look good.
