Got it when they couldn't
In stock and fast shipping was the selling point. My local auto parts stores didn't have this in stock anywhere. I got it in two days and cheaper than they could get it to me. Fits great and works like it should. I'm on top of my maintenance for all my vehicles, so it will get changed on time. Life span should not be an issue.
