That's pretty bad actually. Your HVAC system will thank you for removing the extra restrictions.First time I’ve done this on my frontier, I didn’t even know we had cabin filters till a little while ago, my 03 ranger didn’t have them, not to bad for 5 years worth of debris. I’ve heard some frontiers don’t even come with them installed from the factory. Eek
What a royal pain in the butt to get the second filter back in. Which idiot designed this filter system?
