Not sure why these aren't standard, but a must have. Fits like factory and bolts on rock solid. Easy install and took me about 10 mins. Color matches trim perfectly. Just wish I could've swapped the speaker cover with the JBL marked cover, but the factory uses push tabs and not screws. I didn't want create any loose parts that would vibrate later. For the cost, it isn't a bad accessory. Worth it in my opinion.
