Thanks everyone. I went out and read all the labels on the jeep. It said I had a 3.7L engine (no new news) but nothing said specifics so I posted here. Thanks. I went and swapped at the part store for the right filter. I hope ATP makes good filters.
The only thing my Liby has let me down on was window regulators and I am good at swapping them out. The only major thing was it smoked through its tires in 20K, so I had alignment checked and said it needed a casterkit. So I had it done and aligned and put on some Scorpion tires. I am getting alot of rattle from my passenger door speaker but we dont play music loud so I am thinking the plastic backing on the door is interfering with the speaker making a buzz on deaper base parts but if speaker is blown I will put some Infinity in. But the Liby has been very good to us. I put JTA shorty headers, Maganaflow Catback, and did a custom forced air induction mod to my airbox that scoops cold air from the grip around radiator into the side of the airbox.
