Another great Amazon buy. Don't let the price or the crazy brand name keep you away. When I took the OEM grill off and compared it to this, it was pretty much spot on. All the clips are located in the right place, fits nice & snug and looks great. The most trouble I had was figuring out how to insert the front camera delete. There are no directions or videos explaining it. Once I concluded there's only one logical direction, I held my breath and applied the force that was needed to snap it into place. After that, it was a breeze (thanks to an unaffiliated YouTube video). Time will tell if it holds up (didn't like the other review that showed paint feeling off after a few weeks; not sure what that's about). If mine does the same, I'll surely update my review. For now, Highly Recommended.

As many things made in China you can't expect not to do anything to them. I had to cut or shave off a bit on the clips to make it work. end results put a smile on my face. Still worth the effort. Just keep that in mind or they will fall off.

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
