I have a 2016 Patriot 75th Anni Edition. A couple weeks ago, I replaced the air filter with a K&N Filter, P/N E-1998. Since I have gotten worse gas mileage. Has anyone ran into this? I've read a lot of posts and reviews of how people have gotten better gas mileage, but I haven't found any for worse. I'm gonna double check later today that it's fully seated. I didn't have any problem installing, went on the intake tube no problem. Thank you.
