Check engine light
Style: Gloss Black Single Slat, Size: G20(2019-2022), Style: Gloss Black Single Slat, Size: G20(2019-2022)
Looks good but will throw a check engine light on your car. The fitment isn’t perfect causing the adaptive vents to show that they are failing even though they are not

Quick fix

Easily Installed with no modification in under a minute. The finish was a little glossier, then OE.

Identical to originals at 1/4 of the price.
This is a review on the Kawaski KRX wheel hub covers. I am very impressed. These are identical in look to the OEM Kawasaki KRX hub covers. Those cost over $28.00 for just one. This is a 4 pack for less than that price. The okastic quality is the same and these fit the machine perfectly. We got them to replace as the others break and fall off and you can not tell which one is new compared to the old ones. Overall great buy and identical to the original. Highly recommend.

Fit supper snug!
Awesome product. I lost 2 of them on my Kawasaki Teryx 1000, and these caps fit super snug. I almost didn't think they fit because they were so tight, and had to use a rubber mallet to gentle tap them on. Worth the buy!
