I've not done the plugs on my 2018. However, I had a 2008 Patriot and still have a 2014 Patriot. Same engines as the Compass during those years. I do my plugs about every 35,000, i.e., about every year, usually in the fall. I've heard tell that if you wait too long extracting the old ones can be a problem. I use anti-seize so its not a struggle next time. Frankly, the hardest plugs to remove were the factory plugs. They had me scared, especially when the first one took a lot of effort then kinda jerked loose!
Changing plugs on the 2.0 or 2.4 is about as easy as changing the oil. You'll need an extension to get down there. If memory serves 6" isn't enough.
Most plugs come pre-gapped. I forget the torque spec (you'll have to look it up) but I'm with Grayrider84 above: its important to get the torque right.
HINT: I use the coil pack to get the new plugs started because the rubber boot is gentle and I don't want to risk cross-threading.
