Pull the old filter out in an arc through the space where the downwards facing vent was while squeezing the filter as previously noted by others. To install u simply push the filter in through this space while squeezing the end a bit and just feed it in on an arc (like making a left hand turn kinda)... Occasionally aligning and manipulating the top then bottom back and forth until it is all the way in. It is a pain but it does go in in less than 3minutes... Then just slide the vent over 2 inches to the right and tighten the small bolt.... Install the cover and u r done.
OK - that wasn't the easiest thing I have ever done but using your instructions, I was able to wiggle and squeeze the old one out and the new one in. I don't know if I'm going to be as good about doing it again in 20,000 miles though.
