I ran into the same situation with our '15 T4R -- no XP. The regular Wix worked great for 10k mile interval. Since I was planning to extend, picked up some Amsoil filters which are good for 15k miles. But sadly, ended up selling the Runner and I've got 4 or 5 left. Bought them in 2019 so they're almost 3 years old but still in the plastic bag. PM me if you're interested.
