Nothing better than OEM
Why did you pick this product vs others?: Fit perfectly. Old OEM cap had almost 360,000 miles on it. Was causing an issue with not allowing the radiator to build up proper compression. Once installed, problem went away. I would always recommend OEM when possible.

Economical OEM cooling system repair part
Sister's Buick kept losing coolant. No leaks at any expected mechanical point and vehicle passed pressure test. New radiator cap cured the problem. Old 2007 cap O rings were brittle.
