I went to my local chevy dealer the other day to buy a new cap for my 98 STS. They sold me a 18 PSI cap (the original was 15 PSI) and although it fits, it looks like a totally different design than my original cap. Also it clicks when I tighten it. the original just screws on till its tight. I called the parts guy and he said that is whats listed for my application. All input appreciated. Thanks.
