I recommend it.

I bought this for my 2011 Chevy Silverado with the LC9 engine, and so far, it's been working great. Time will tell how well it holds up, but after about 100 miles, it's performing solidly. I was a little skeptical at first, but I'd definitely recommend it. I usually stick with OEM parts, especially since my engine has 6,884 hours and counting, but this is the first aftermarket part I've tried—and I'm very pleased with it. If you don't believe the hours, I included a picture. The coolant you see isn't from the cap—I just spilled a little while changing.

OEM legit

Original cap, bought from Amazon and they sent me a fake one but this one from Walmart is legit and fixed my bubbling problem.
