Hey all. Just bought myself a new to me 01 Grand Cherokee 4.7L. Thought I would join the forum and start learning as much as I could about it. It is going to be my wife’s daily driver so I want to keep the ride nice and road responsive. But I am open to upgrading what you all suggest will help with mpg, comfort and safety. She will have my son in it frequently and I want them to be as safe as possible. Any help would be greatly appreciated. Thank you all and have a great December.
